* 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
* update tests to expose bug in React implementation
* fix incorrect `active` state on mouseLeave
The React code had a bug in the Listbox and Combobox components where it
incorrectly made the first selected value the active value.
The first selected option should be the active option when you open the
listbox. However when you already had the component in an `open` state,
hovered over a non-selected item and them left the option by moving it
to the body then the first selected option became the active one again.
This made sense because we used a `useEffect` in each option to make it
the active one if it was also selected. Since every component
re-renders, code got called and the bug arises.
Now, instead we moved the logic to make it the active option to the
reducer logic. We will check it when we register an option and doesn't
have an active option index yet or when we open the Listbox/Combobox.
This should also solve the strange scrolling behaviour where the options
scroll up if you have more options than you display.
* update changelog
* improve Tree Shaking in ESM
Instead of bundling everything into a single ESM file, we generate every
single file as ESM. This is what we did in 1.4.x as well.
I would expect if your library had a single ESM file and you only used 1
function that the application you use it in correctly does the
tree-shakign for you. Apparantly a lot of applications are not properly
setup for this, so let's create multiple files instead.
* update changelog
* First attempt at a multi-listbox
* implement `multiple` mode on Listbox
* add multiple Listbox example to playground
* implement `multiple` mode on Combobox
* make sure groupContext is not undefined or null
On vercel, getting a strange issue like `TypeError: undefined is not an
object (evaluating 'r.resolveTarget')` which doesn't happen locally or
once published. Would expect it to be `null` since we default to `null`.
Hopefully this fixes things.
* bump all the dependencies
* make sure that `@types/react` use set to the correct version
`@types/react-dom` hardcoded the `@types/react` to version `16.14.21`
instead of using the latest `16.14.24` resulting in type mismatches.
*cries in inconsistency*
* update changelog
* add multiple Combobox example to playground
* refactor Combobox, use actions
* use combobox data
This is a first step in refactoring everything where we use dedicated
actions and data instead of accessing the reducer state directly.
It also allows us to get rid of mutations in render where we updated
some values in render directly which is not ideal.

* 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
* re-expose `el`
We used to expose a custom `el` when we used a `setup()` and `render()`
function. But due to some refactors we got now only have a `setup()` and
no more `el`. This causes some problems if people relied on the exposed
`el`.
In this PR will make sure to re-expose the `el` that we used to expose.
The only issue is, now that we manually expose a list, we have to
re-expose the `$el` internal as well.
* update changelog
* remove raw `document.getElementById` calls
When we introduced the `forwardRef` for all components, we also made
sure that internal `ref`s were used to keep track of the actual DOM
node.
This code prefers the `internalXXRef` refs in favor of the
`document.getElementById` calls. This is way more React-ish, and also
fixes a few issues:
- Potential performance improvements (no need to re-query the DOM, since
we already have a reference to the DOM node). Note: this is a *guess*,
I didn't measure this.
- It could be that the element is rendered in another `document`, the
correct would involve something like
`someDOMNode.ownerDocument.getElementById(...)` but that should not be
necessary anymore now.
* make Disclosure implementation between React & Vue consistent
* use a similar convention for DOM refs to other components
* update changelog
* cleanup auto-scrolling
We keep the actual container focused, so we don't require the invidiual
option to be focused as well. We do want to scroll it into view but
that's part of another piece of code.
Also cleaned up some manual `document.querySelector` calls now that we
keep track of a `ref`.
* 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" />
```

* fix restoreElement logic
The code for React already worked, let's update the Vue code to make it
similar which properly restores focus.
* update changelog
* adjust active {item,option} index
We had various ordering issues, and now we properly sort all the notes
which is awesome. However, there is this case where we still use the
`activeOptionIndex` / `activeItemIndex` from _before_ the sort happens.
Now we will ensure that this is properly adjusted when performing the
sort of the items.
In addition, we will also properly adjust these values when
`registering` and `unregistering` items, not only when performing
actions.
* update changelog
* prevent initial transitioning in SSR environment
Due to SSR and the hydration step, the transition code was already
called even if we were not ready yet. This caused an issue where the
`beforeEnter` callback got fired twice intead of once.
Fixes: #311
* update changelog
* ensure that `appear` works regardless of multiple rerenders
* remove incorrect `afterLeave` call
* update changelog
* only set the prevShow when using the unmount strategy
* improve outside click support
We used to use `pointerdown`, but some older devices with iOS 12 didn't
have support for that. Instead we used `mousedown`. But now it turns out
that some devices only properly use `pointerdown` and not the `mousedown` event.
Instead, we will listen to both, but make sure to only handle the event
once.
* update changelog
* Fix React transition bug
* use a ref instead of a useCallback (#1108)
This allows us to guarantee that the ref is always referencing the
latest callback. This also allows us to re-run fewer effects because we
don't really care about intermediate callback values, just the last one.
* Fix tests
* Update changelog

* ensure proper sort order
We already fixed a bug in the past where the order of DOM nodes wasn't
stored in the correct order when performing operations (e.g.: using your
keyboard to go to the next option).
We fixed this by ensuring that when we register/unregister an
option/item, that we sorted the list properly. This worked fine, until
we introduced the Combobox components. This is because items in a
Combobox are continuously filtered and because of that moved around.
Moving a DOM node to a new position _doesn't_ require a full
unmount/remount. This means that the sort gets messed up and the order
is wrong when moving around again.
To fix this, we will always perform a sort when performing actions. This
could have performance drawbacks, but the alternative is to re-sort when
the component gets updated. The bad part is that you can update a
component via many ways (like changes on the parent), in those
scenario's you probably don't care to properly re-order the internal
list. Instead we do it while performing an action (`goToOption` / `goToItem`).
To make things a bit more efficient, instead of querying the DOM all the
time using `document.querySelectorAll`, we will keep track of the
underlying DOM node instead. This does increase memory usage a bit but I
think that this is a fine trade-off.
Performance wise this could also be a bottleneck to perform the sorting
if you have a lot of data. But this problem already exists today,
therefore I consider this a complete new problem instead to solve. Maybe
we don't solve it in Headless UI itself, but figure out a way to make it
composable with existing virtualization libraries.

* only record the restoreElement once enabled
Currently we are collecting the `restoreElement` even if the focus trap
is not enabled. When we unmount we try to restore it.
The problem is the moment you unmount you want to restore but only if
the focus trap was enabled.
Another issue is that the dialog state will be `closed` before we get to
the `onUmount` hook. So there is probably a cleaner way to fix this, but
this does the trick as well where we only record the restoreElement the
moment the focus trap gets enabled.
* update changelog
* forward ref to all components
* fix playground pages
This isn't a perfect fix of course. But the TypeScript changes required
to do it properly are a bit bigger and require more work.
Having this ready is a good step forward.
* update changelog
* ensure that you can close the combobox initially
The issue is that `onInput` fires on every keystroke, and we also
handled `onChange` which is triggered on blur in Vue.
This means that the moment we blur, we also called the `handleChange`
code to re-open the combobox because we want to open the combobox if
something changes when the user starts typing.
To fix this, we will splitup the logic so that it will only open the
combobox on input but not on change.
* update changelog
* improve concurrency of GitHub Actions
This will allow you to cancel older running actions for the current PR /
branch. This saves you some resources, but more importantly hopefully
frees up some spots in the queue a bit faster.
Saw this on the Node.js repo: https://github.com/nodejs/node/pull/42017
* empty commit to trigger cancellation of previous commit
* trigger scrollIntoView effect when position changes
This is important otherwise it could happen that the current active item
is still the active item even if we inserted X items before the current
one. This will result in the active item being out of the current
viewport. To fix this, we will also make sure to trigger the effect if
the position of the active item changes.
* update changelog
* bubble Escape event even if `Combobox.Options` is not rendered at all
If you use `<Combobox.Options static />` it means that you are in
control of rendering and in that case we also bubble the `Escape`
because you are in control of it.
However, if you do something like this:
```js
{filteredList.length > 0 && (
<Combobox.Options static>
...
</Combobox.Options>
)}
```
Then whenever the `filteredList` is empty, the Combobox.Options are not
rendered at all which means that we can't look at the `static` prop. To
fix this, we also bubble the `Escape` event if we don't have a
`Combobox.Options` at all so that the above example works as expected.
* update changelog
* ensure combobox option gets activated on hover (while static)
* rename combobox test file
* remove leftover `horizontal` prop
* remove unnecessary handleLeave calls
These are implemented on the `Combobox.Option` instead of the
`Combobox.Options`. This allows you to have additional visual padding
between `Combobox.Options` and `Combobox.Option` and if you hover over
that area then the option becomes inactive.
If we implement it on the `Combobox.Options` instead then this isn't
_that_ easy to do. We can do it by checking the target and whether or
not it is inside a headlessui-combobox-option. This would only have a
single listener instead of `N` listeners though. Potential improvements!
* implement `hold` in favor of `latestActiveOption`
* update changelog
* Allow Escape to bubble when options is static
You’ve taken control of the open/close state yourself in which case this should be allowed to be handled by other event handlers
