* bump React & React DOM dependencies
* fix typo `TOmitableProps` → `TOmittableProps`
* bump prettier
* run prettier after prettier version bump
* bump TypeScript
* run prettier after TypeScript version bump
* enable `verbatimModuleSyntax`
This ensures all imported types are using the `type` keyword.
* add `type` to type related imports
* add common testing scenarios
Will be used in the new and existing components.
* add script to make Next.js happy
Right now Next.js does barrel file optimization and re-writing imports
to a real path in the `dist` folder. Most of those rewrites don't
actually exist because they have an assumption:
```js
import { FooBar } from '@headlessui/react'
```
is rewritten as:
```js
import { FooBar } from '@headlessui/react/dist/components/foo-bar/foo-bar'
```
This script will make sure these paths exist...
* improve `by` prop, introduce `useByComparator`
This hook has a default implementation when comparing objects. If the
object contains an `id`, then we will compare the objects by their
`id`'s without the user of the library needing to specify `by="id"`.
If the objects don't have an `id` prop, then the default is still to
compare by reference (unless specicified otherwise).
* sync yarn.lock
* rename `Features` to `HiddenFeatures` for `Hidden` component
* rename `Features` to `FocusTrapFeatures` in `FocusTrap` component
* rename `Features` to `RenderFeatures` in `render` util
* add `floating-ui` as a dependency + introduce internal floating related components
* bump Vue dependencies
* ensure scroll bar calculations can't go negative
* improve types in `@headlessui/vue`
* use snapshot tests for `Transition` tests in `@headlessui/vue`
* use snapshot tests for `portal` tests in `@headlessui/vue`
* rename `src/components/transitions/` to `src/components/transition/` (singular)
This is so that we can be consistent with the other components.
* drop custom `toMatchFormattedCss`, prefer snapshot tests instead
* use snapshot tests for `Label` tests in `@headlessui/vue`
* use snapshot tests for `Description` tests in `@headlessui/vue`
* sort exported components in tests for `@headlessui/vue`
* use snapshot tests in `@headlessui/tailwindcss`
* rename `mergeProps` to `mergePropsAdvanced`
This is a more complex version of a soon to be exported `mergeProps`
that we will be using in our components.
* do not expose `aria-labelledby` if it is only referencing itself
* expose boolean state as `kebab-case` instead of `camelCase`
These are the ones being exposed inside `data-headlessui-state="..."`
* expose boolean data attributes
A slot with `{active,focus,hover}` will be exposed as:
```html
<span data-headlessui-state="active focus hover"></span>
```
But also as boolean attributes:
```html
<span data-active data-focus data-hover></span>
```
* improve internal types for `className` in `render` util
* ensure we keep exposed data attributes into account when trying to forward them to the component inside the `Fragment`
* add small typescript type fix
This is internal code, and the public API is not influenced by this
`:any`. It does make TypeScript happy.
* introduce `mergeProps` util to be used in our components
This will help us to merge props, when event handlers are available they
will be merged by wrapping them in a function such that both (or more)
event handlers are called for the same `event`.
* add new internal `Modal` component
* fix: when using `Focus.Previous` with `activeIndex = -1` should start at the end
* prefer `window.scrollY` instead of `window.pageYOffset`
Because `window.pageYOffset` is deprecated.
* add `'use client'` directives on client only components
These components use hooks that won't work in server components and you
will receive an error otherwise.
* drop `import 'client-only'` in favor of the `'use client'` directive
* add React Aria dependencies
* pin beta dependencies
* prettier bump formatting
* improve TypeScript types in tests
* use new Jest matchers instead of deprecated ones
* improve typescript types in Vue
* prefer `useLabelledBy` and `useDescribedBy`
* add internal `DisabledProvider`
* add internal `IdProvider`
* add internal `useDidElementMove` hook
* add internal `useElementSize` hook
* add internal `useIsTouchDevice` hook
* add internal `useActivePress` hook
* use snapshot tests for `Description` tests
* use snapshot tests for `Label` tests
* use snapshot tests for `Portal` tests
* use snapshot tests for `render` tests
* add (private) `Tooltip` component
Currently this one is not ready yet, so its not publicly exposed yet.
* add internal `FormFields` component
This one adds a component to render (hidden) inputs for native form
support. It also ensures that form fields can be hoisted to the end of
the nearest `Field`. If the components are not inside a `Field` they
will be rendered in place.
* add new `Button` component
* add new `Checkbox` component
* add new `DataInteractive` component
* add new `Field` component
* add new `Fieldset` component
* add new `Legend` component
* add new `Input` component
* add new `Select` component
* add new `Textarea` component
* export new components
* WIP
* remove `within: true`
This only makes sense if anything inside the current element receives
focus, which is not the case for `input`, `select`, `textarea` or
`Radio/RadioOption`.
* group focus/hover/active hooks together
* conditionally link anchor panel
* immediately focus the container
* prevent premature disabling of `Listbox`'s floating integration
+ Track whether the button moved or not when disabling such that we can
disable the transitions earlier.
* improve scroll locking on iOS
* skip hydration tests for now
* skip certain focus trap tests for now
* update CHANGELOG.md
* add missing requires
* drop unused `@ts-expect-error`
* ignore type issues in playgrounds
These playgrounds are mainly test playgrounds. Lower priority for now,
we will get back to them.
* add yarn resolutions to solve swc bug
* add `prettier-plugin-organize-imports` and `prettier-plugin-tailwindcss`
* format
* bump Tailwind CSS
* format playgrounds using updated Tailwind CSS and Prettier plugins
* use import syntax
* explicitly add the `aria-hidden="true"` attribute
The `Hidden` component only adds the `aria-hidden` by default if the
`Focusable` feature is passed. In our case we don't want it to be
focusable so therefore we didn't pass this feature flag.
Because we didn't pass the `Focusable` feature, the `display: hidden`
was used which makes it completely unfocusable to the keyboard of the
user which is what we want.
However, the VoiceOver cursor _can_ get into those elements. Adding the
`aria-hidden` manually to these tabs solves the issue.
* update changelog
* Skip updating state if sentinel has been unmounted
* use existing `useIsMounted` hook
* reformat code paths

* cleanup `XYZPropsWeControl`
The idea behind the `PropsWeControl` is that we can omit all the fields
that we are controlling entirely. In this case, passing a prop like
`role`, but if we already set the role ourselves then the prop won't do
anything at all. This is why we want to alert the end user that it is an
"error".
It can also happen that we "control" the value by default, but keep
incoming props into account. For example we generate a unique ID for
most components, but you can provide your own to override it. In this
case we _don't_ want to include the ID in the `XYZPropsWeControl`.
Additionally, we introduced some functionality months ago where we call
event callbacks (`onClick`, ...) from the incoming props before our own
callbacks. This means that by definition all `onXYZ` callbacks can be
provided.
* improve defining types
Whenever we explicitly provide custom types for certain props, then we
make sure to omit those keys first from the original props (of let's say
an `input`). This is important so that TypeScript doesn't try to "merge"
those types together.
* cleanup: move `useEffect`
* add `defaultValue` explicitly
* ensure tests are not using `any` because of `onChange={console.log}`
The `console.log` is typed as `(...args: any[]) => void` which means
that it will incorrectly mark its incoming data as `any` as well.
Converting it to `x => console.log(x)` makes TypeScript happy. Or in
this case, angry since it found a bug.
This is required because it _can_ be that your value (e.g.: the value of
a Combobox) is an object (e.g.: a `User`), but it is also nullable.
Therefore we can provide the value `null`. This would mean that
eventually this resolves to `keyof null` which is `never`, but we just
want a string in this case.
```diff
-export type ByComparator<T> = (keyof T & string) | ((a: T, b: T) => boolean)
+export type ByComparator<T> =
+ | (T extends null ? string : keyof T & string)
+ | ((a: T, b: T) => boolean)
```

* improve the internal types of the `Disclosure` component
* improve the internal types of the `Listbox` component

* improve the internal types of the `Popover` component
* improve the internal types of the `Tabs` component
* improve the internal types of the `Transition` component
* use `Override` in `Hidden` as well
* cleanup unused code
* don't check the `useSyncExternalStoreShimClient`
* don't check the `useSyncExternalStoreShimServer`
* improve types in the render tests
* fix `Ref<TTag>` to be `Ref<HTMLElement>`
* improve internal types of the `Transition` component (Vue)
+ add `attrs.class` as well
* use different type for `AnyComponent`
* update changelog
* introduce `opening` and `closing` states
Also represent them as bits so that we can easily combine them while we
are transitioning from one state to the other.
* update `open/closed` state checks
Instead of checking whether it is in one state or an other, we can check
if the current state contains some potential sub-state.
This allows us to still check if we are in the `Open` state, while also
`Closing` because the state will be `S.Open | S.Closing`.
* expose `flags` from the `useFlags` hook
* add the `Closing` and `Opening` states to the Open/Closed state
* create dedicated `abcEnabled` variables
* keep the `State.Closing` into account for `scroll locking` and `inert others`
* add a test for the `Closing` state impacting the `Dialog` component
* cleanup unused imports
* add `unmount` util to the Vue Test renderer
* update changelog
* use the `import * as React from 'react'` pattern
We use named imports, but we have to import `React` itself as well for
JSX because it compiles to `React.createElement`. We could get rid of
our own JSX and use it directly, or we can use this `import * as React
from 'react'` syntax.
This fixes an issue for people using `allowSyntheticDefaultImports: false` in TypeScript.
Fixes: #2117
* update changelog
* Don’t close dialog if opened during mouse up event
* Don’t close dialog if drag starts inside dialog and ends outside dialog
* Handle closing of nested dialogs that are always mounted
* Fix focus trap restoration in Vue
* Update changelog
* sort React imports
* improve type signature of the `useEvent` hook
* use more correct `useIsoMorphicEffect` check in `useEvent`
* refactor `useCallback` to cleaner `useEvent`
* convert `const` to `let`
Just for consistency..
* cleanup `Tabs` code
Created explicit functions that can be called from child components
instead of calling `dispatch` directly. Introduced a `useData` and
`useActions` hook to make child components easier.
The seperation of `useData` allows us to pass down props directly
instead of going via the `useReducer` hook and dispatching actions to
make values up to date.
* cleanup `Combobox` code
* cleanup `RadioGroup` code
* refactor `VisuallyHidden` to `Hidden` component
This new component will also make sure that it is visually hidden to
sighted users. However, it contains a few more features that are going
to be useful in other places as well. These features include:
1. Make visually hidden to sighted users (default)
2. Hide from assistive technology via `features={Features.Hidden}`
(will add `display: none;`)
3. Hide from assistive technology but make the element focusable via
`features={Features.Focusable}` (will add `aria-hidden="true"`)
* add `useEvent` hook
This will behave the same (roughly) as the new to be released `useEvent`
hook in React 18.X
This hook allows you to have a stable function that can "see" the latest
data it is using. We already had this concept using:
```js
let handleX = useLatestValue(() => {
// ...
})
```
But this returned a stable ref so you had to call `handleX.current()`.
This new hook is a bit nicer to work with but doesn't change much in the
end.
* add `useTabDirection` hook
This keeps track of the direction people are tabbing in. This returns a
ref so no re-renders happen because of this hook.
* add `useWatch` hook
This is similar to the `useEffect` hook, but only executes if values are
_actually_ changing... 😒
* add `microTask` util
* refactor `useFocusTrap` hook to `FocusTrap` component
Using a component directly allows us to simplify the focus trap logic
itself. Instead of intercepting the <kbd>Tab</kbd> keydown event and
figuring out the correct element to focus, we will now add 2 "guard"
buttons (hence why we require a component now). These buttons will
receive focus and if they do, redirect the focus to the first/last
element inside the focus trap.
The sweet part is that all the tabs in between those buttons will now be
handled natively by the browser. No need to find the first non disabled,
non hidden with correct tabIndex element!
* refactor the `Dialog` component to use the `FocusTrap` component
Also added a hidden button so that we know the correct "main" tree of
the application. Before this we were assuming the previous active
element which will still be correct in most cases but we don't have
access to that anymore since the logic is encapsulated inside the
FocusTrap component.
* ensure `<Portal />` properly cleans up
We make sure that the Portal is cleaning up its `element` properly.
We also make sure to call the `target.appendChild(element)`
conditionally because I ran into a super annoying bug where a focused
element got blurred because I believe that this re-mounts the element
instead of 'moving' it or just ignoring it, if it already is in the
correct spot.
* refactor: use `useEvent` instead of `useLatestValue`
Not really necessary, just cleaner.
* update changelog
* improve rendering of hidden form fields
* add `attemptSubmit` helper
This will allow us to _try_ and submit a form based on any element you
pass it. It will try and lookup the current form and if it is
submittable it will attempt to submit it.
Instead of submitting the form directly, we try to follow the native
browser support where it looks for the first `input[type=submit]`,
`input[type=image]`, `button` or `button[type=submit]`, then it clicks
it.
This allows you to disable your submit button, or have an `onClick` that
does an `event.preventDefault()` just like the native form in a browser
would do.
* ensure we can submit a form from a closed Combobox
When the Combobox is closed, then the `Enter` keydown event will be
ignored and thus not use `event.preventDefault()`.
With recent changes where we always have an active option, it means that
you will always be able to select an option.
If we have no option at all (some edge case) or when the combobox is
closed, then the `Enter` keydown event will just bubble, allowing you to
submit a form.
Fixes: #1282
This is a continuation of a PR ([#1176](https://github.com/tailwindlabs/headlessui/pull/1176)) provided by Alexander, so wanted to include
them as a co-author because of their initial work.

* ensure we can submit a form from a RadioGroup
* ensure we can submit a form from a Switch
* simplify / refactor form playground example
* update changelog
Co-authored-by: Alexander Lyon <arlyon@me.com>
* rename inconsistent `passThroughProps` and `passthroughProps` to more
concise `incomingProps`
This is going to make a bit more sense in the next commits of this
branch, hold on!
* split props into `propsWeControl` and `propsTheyControl`
This will allow us to merge the props with a bit more control. Instead
of overriding every prop from the user' props with our props, we can now
merge event listeners.
* update `render` API to accept `propsWeControl` and `propsTheyControl`
* improve the merge logic
This will essentially do the exact same thing we were doing before:
```js
let props = { ...propsTheyControl, ...propsWeControl }
```
But instead of overriding everything, we will merge the event listener
related props like `onClick`, `onKeyDown`, ...
* fix typo in tests
* simplify naming
- Rename `propsWeControl` to `ourProps`
- Rename `propsTheyControl` to `theirProps`
* update changelog
* add internal FocusSentinel component
This component will allow you to catch the focus and forward it to a new
element. The catch is that it will retry to do that because sometimes
components won't be available yet.
E.g.: We want to focus the first Tab component if it is rendered inside
the Dialog. However, a Tab will register itself in the next tick,
triggering a re-render and only then will it be `selected`. This is a
bit too late for the FocusTrap component.
The FocusSentinel should fix this by catching the focus, and forwarding
it to the correct component. Once that is done, it will remove itself
from the DOM tree so that you can't ever focus that element anymore.
This should fix potential `<tab>` and `<shift+tab>` behaviour.
* find the selectedIndex asap
* use the FocusSentinel and forward it to the correct Tab
* add example Tab in Dialog example
* suppress console warnings
Because we are firing `setState` calls within the component, React is
yelling at us for not using `act(() => { ... })`. Welp, not going to add
those calls inside the component just for tests...
* update changelog
* implement `objetToFormEntries` functionality
If we are working with more complex data structures then we have to
encode those data structures into a syntax that the HTML can understand.
This means that we have to use `<input type="hidden" name="..." value="...">` syntax.
To convert a simple array we can use the following syntax:
```js
// Assuming we have a `name` of `person`
let input = ['Alice', 'Bob', 'Charlie']
```
Results in:
```html
<input type="hidden" name="person[]" value="Alice" />
<input type="hidden" name="person[]" value="Bob" />
<input type="hidden" name="person[]" value="Charlie" />
```
Note: the additional `[]` in the name attribute.
---
A more complex object (even deeply nested) can be encoded like this:
```js
// Assuming we have a `name` of `person`
let input = {
id: 1,
name: {
first: 'Jane',
last: 'Doe'
}
}
```
Results in:
```html
<input type="hidden" name="person[id]" value="1" />
<input type="hidden" name="person[name][first]" value="Jane" />
<input type="hidden" name="person[name][last]" value="Doe" />
```
* implement VisuallyHidden component
* implement and export some extra helper utilities
* implement form element for Switch
* implement form element for Combobox
* implement form element for RadioGroup

* add combined forms example to the playground
* update changelog
* enable support for iterators
* ensure to compile dom iterables
* remove unused imports
* add tests to verify the nested Dialog behaviour
* set mounted to true once rendered once
* cache useWindowEvent listener
We only care about the very last version of the listener function. This
allows us to only change the event listener if the event name (string)
and options (boolean | object) change.
* add/delete messages when mounting/unmounting
We don't require a dedicated hook anymore, so this is a bit of cleanup!
* add comments to the FocusResult enum
* splitup functionality and make it a bit more clear using feature flags
* add getDialogOverlays helper
* simplify the Portal component
We don't need to add the current element to the Stack. We only want to
take care of that in the Dialog component itself.
* drop dom-containers
Currently it is only used in a single spot, so I inlined it into that
file.

* improve Dialog component
* update CHANGELOG
* simplify examples by using the implicit open/closed state
* introduce Open/Closed context (React)
* use Open/Closed context in Dialog component (React)

* use Open/Closed context in Menu component (Vue)
* use Open/Closed context in Popover component (Vue)
* use Open/Closed context in Transition component (Vue)
* use a ref in the Description comopnent
This allows us to update the ref and everything should work after that.
Currently we only saw the "current" state.
* add more Vue examples
* update changelog
* add little editor hack
By adding a html`..` to the template strings editors can get syntax
highlighting for these template strings. Even better, prettier can even
format the contents inside those because now it is "aware" of what kind
of content is inside of these template strings.
You might notice that for the Menu component I have a jsx`..`, this is
another little hack, this only provides us with syntax highlighting and
not with prettier support.
The reason why we have this is that for some reason, when you have:
html`
<MenuItem>
`
It will be formatted as:
html`
<menuitem>
`
There might exist a better name we can use instead of jsx, but for now,
this will do. Having syntax highlighting is already 10x better than what
we had before!

* expose Alert component
* add Disclosure component

* update test utils
We've been making some changes in the React utils, so we have to update
them here as well!
* add Popover component
* expose Popover
* drop unused state
* type Disclosure's API object
* add Portal component
* add Portal example
* expose Portal component
* use correct containElement assertion
* add useInertOthers hook
* add Dialog component
* fix various typo's
* expose Dialog
* add Popover example
* force focus on the Popover button on click
* drop own id when using labels
We are nesting the Label and Description components, if we also add the
id of ourselves we get strange results when using Voice Over.
First you would hear the contents (which includes the labels and
descriptions) then you would hear the labels and descriptions again.
We don't want to hear things twice!
* add Dialog example
* ensure to stop propagation
Otherwise if you nest a Menu inside a Dialog and you press `Escape` the
Dialog will close as well, which is not the expected behaviour.
* improve focus management
When you trigger a Popover using a `click` event, then start using `Tab`
the next `a`-tags do not contain the default focus styles. These only
happen when you trigger it using the keyboard first.
Using a tabindex="0" does make it "focusable" and the default browser
styles will be visible. If we remove the tabindex in a
requestAnimationFrame or a setTimeout then the focus styles will be
removed as well.
This should not cause to many issues (fingers crossed) because the
document.activeElement was already referring to the correct element!
* remove Alert component
There are a lot of unknowns and context dependendant questions to
implement Alerts in a good way. The current Alert component just had a
role set, and it had no JS attached.
We will revisit this, once we start working on Alert Dialogs,
Notification center notifications (dismissable, hide after x time, ...)
* ensure Popover.Overlay auto shows/hides based on Popover state
* enable focus trapping based on `open` prop
Only enable focus trapping in the Dialog when `open` is true, regardless
of the `static` prop.
* handle attrs on Dialog manually
* add low level Description component
* add low level Label component
* add RadioGroup component
* expose RadioGroup
* update README with links to new components
* update changelog with all the changes
* add RadioGroup example
* improve type in test
* cleanup internal Dialog Description
We have a low level Description component abstraction that can be used
instead of the Dialog specifiction Description.
* refactor raw window events to a shared useWindowEvent
* passthrough prop bag via context for abstract Description
The Description component is a generic low level component that is
re-used. This causes an issue that the render prop "bag"/"slot" doesn't
contain the data from let's say a Dialog component.
This commit will ensure that you can specify a bag (React) and slot
(Vue) on the DescriptionProvider, so that the Description component can
read it from the context.
* improve render function in React
These contain a few changes that are purely internal changes. Nothing
changes / breaks in the public API of the components.
- Instead of using multiple arguments in your `render()` functions, we now
use an object.
- `propsBag` / `bag` is renamed to `slot`.
- We also provide a `name` to the render function, so that we can use
that to improve error messages.
* use the new internal render api (React)
* improve render function in Vue
* use the new internal render api (Vue)
* add Alert component
* expose Alert
* rename forgotten FLYOUT to POPOVER
* use PopoverRenderPropArg
* organize imports in a consistent way
* ensure Portals behave as expected
Portals can be nested from a React perspective, however in the DOM they
are rendered as siblings, this is mostly fine.
However, when they are rendered inside a Dialog, the Dialog itself is
marked with `role="modal"` which makes all the other content inert. This
means that rendering Menu.Items in a Portal or an Alert in a portal
makes it non-interactable. Alerts are not even announced.
To fix this, we ensure that we make the `root` of the Portal the actual
dialog. This allows you to still interact with it, because an open modal
is the "root" for the assistive technology.
But there is a catch, a Dialog in a Dialog *can* render as a sibling,
because you force the focus into the new Dialog. So we also ensured that
Dialogs are always rendered in the portal root, and not inside another
Dialog.
* add dialog with alert example
* add internal Description component
* add internal Label component
* add RadioGroup component
* expose RadioGroup
* add RadioGroup example
* ensure to include tha RadioGroup.Option own id
* update changelog
* split documentation
* apply re-focus bug fix to Popover
* force focus in Menu.Items from within Menu.Items component itself
* force focus in Listbox.Options from within Listbox.Options component itself
* fix undefined values in id's
We were setting the element in state, but updates to the id were not taken into account
* update the caniuse db
* ensure useInertOthers works in multiple places
Previously each hook call would take care of the whole tree. However
when multiple calls to this hook are happening we need to make sure that
you are not removing the aria-hidden when another hook is still used.
This will fix that by keeping track of a list of "interactable" items,
and updating the parents (root of the body) accordingly.
* add the concept of a Stack
When you are rendering a Dialog, we will make sure that this Dialog is
rendered inside a Portal. However, when you are also rendering a Menu,
there is a chance that your Menu doesn't fit within the Dialog,
therefore you will likely render the Menu.Items inside a Portal so that
you can style it as if it is rendered inside but overflows the Dialog
correctly.
This introduces an interesting/annoying problem. Your Menu.Items are now
rendered in a Portal, as a *sibling* to the Dialog. This means that
autoFocus, focusTrap, ... all these features don't work as expected.
Introducing this Stack will allow us to register DOM nodes into a list
of contains that we consider being part of the main container. In other
words, the sibling Menu.Items will now be considered part of the Dialog.
Even though it is rendered *outside* of the Dialog.
This concept also allows for some fun stuff, for example, nesting
Dialog's is no problem with this approach. Dialogs are technically
rendered as siblings in the Portal, but the FocusTrap, and all that just
works as expected.
* capture keyboard events in the capturing phase
This will allow us to use event.stopPropagation() in the code (which
will be required, probably) but still see the keystrokes in the
playground.
* stop propagating keyboard events
This looks a bit silly, and ideally we can solve this in a more elegant
way. However when you nest a Menu inside a Dialog, both of those
components have a `close on escape` functionality built in. However when
your Menu is open, and you press escape, you only want to close the
Menu, not the Dialog. Therefore if we `event.stopPropagation()` it
allows us to stop the `escape` keystroke in the Menu from reaching all
the way to the Dialog itself.
* update Dialog example that showcases nested Dialogs, and nested Menu
* update changelog
