* update playground examples to use a shared `Button`
* expose a `ui-focus-visible` variant
* keep track of a `data-headlessui-focus-visible` attribute
* do not set the `tabindex`
The focus was always set, but the ring wasn't showing up. This was also
focusing a ring when the browser decided not the add one.
Let's make the browser decide when to show this or not.
* update changelog
* add reset button to form example
* refactor React Listbox
This splitsup the raw `[state, dispatch]` to separate `useActions` and `useData` hooks.
This allows us to make the actions themselves simpler and include logic
that doesn't really belong in the reducer itself.
This also allows us to expose data via the `useData` hook that doesn't
belong in the state exposed from the `useReducer` hook.
E.g.: we used to store a `propsRef` from the root `Listbox`, and update
the ref with the new props in a `useEffect`. Now, we will just expose
that information directly via the `useData` hook. This simplifies the
code, removes useEffect's and so on.
* refactor Tabs, ensure function reference stays the same
If the `isControlled` value changes, then the references to all the
functions changed. Now they won't because of the `useEvent` hooks.
* type the actions abg similar to how we type the data bag
* refactor RadioGroup to use useData/useActions hooks
* reset Listbox to defaultValue on form reset
* reset Combobox to defaultValue on form reset
* reset RadioGroup to defaultValue on form reset
* reset Switch to defaultChecked on form reset
* port combinations/form playground example to Vue
* update changelog
* implement uncontrolled form components
A few versions ago we introduced compatibility with the native `form`
element. This means that behind the scenes we render hidden inputs that
are kept in sync which allows you to submit your normal form and get
data via `new FormData(event.currentTarget)`.
Before this change every form related component (Switch, RadioGroup,
Listbox and Combobox) always had to be passed a `value` and an
`onChange` regardless of this change.
This change will allow you to not even use the `value` and the
`onChange` at all and keep it completely uncontrolled.
This has some changes:
- `value` is made optional
- `onChange` is made optional (but will still be called if passed
regardless of being controlled or uncontrolled)
- `defaultValue` got added so that you can still pre-fill your values
with known values.
- `value` render prop got exposed so that you can still use this while
rendering.
This should also make it completely compatible with tools like Remix
without wiring up your own state.
* update example combinations/form playground to use uncontrolled
components
* improve types, add missing render prop arguments
* add tests for uncontrolled components (React)
* implement uncontrolled form elements in Vue
* check typeof document in addition to typeof window
* remove unused import
* Extract SSR check to a central spot
* Fix CS

* convert dialog in playground to use Dialog.Panel
* convert `tabs-in-dialog` example to use `Dialog.Panel`
* add scrollable dialog example to the playground
* simplify `outside click` behaviour
Here is a little story. We used to use the `click` event listener on the
window to try and detect whether we clicked outside of the main area we
are working in.
This all worked fine, until we got a bug report that it didn't work
properly on Mobile, especially iOS. After a bit of debugging we switched
this behaviour to use `pointerdown` instead of the `click` event
listener. Worked great! Maybe...
The reason the `click` didn't work was because of another bug fix. In
React if you render a `<form><Dialog></form>` and your `Dialog` contains
a button without a type, (or an input where you press enter) then the
form would submit... even though we portalled the `Dialog` to a
different location, but it bubbled the event up via the SyntethicEvent
System. To fix this, we've added a "simple" `onClick(e) { e.stopPropagation() }`
to make sure that click events didn't leak out.
Alright no worries, but, now that we switched to `pointerdown` we got
another bug report that it didn't work on older iOS devices. Fine, let's
add a `mousedown` next to the `pointerdown` event. Now this works all
great! Maybe...
This doesn't work quite as we expected because it could happen that both
events fire and then the `onClose` of the Dialog component would fire
twice. In fact, there is an open issue about this: #1490 at the time of
writing this commit message.
We tried to only call the close function once by checking if those
events happen within the same "tick", which is not always the case...
Alright, let's ignore that issue for a second, there is another issue
that popped up... If you have a Dialog that is scrollable (because it is
greater than the current viewport) then a wild scrollbar appears (what a
weird Pokémon). The moment you try to click the scrollbar or drag it the
Dialog closes. What in the world...?
Well... turns out that `pointerdown` gets fired if you happen to "click"
(or touch) on the scrollbar. A click event does not get fired. No
worries we can fix this! Maybe...
(Narrator: ... nope ...)
One thing we can try is to measure the scrollbar width, and if you
happen to click near the edge then we ignore this click. You can think
of it like `let safeArea = viewportWidth - scrollBarWidth`. Everything
works great now! Maybe...
Well, let me tell you about macOS and "floating" scrollbars... you can't
measure those... AAAAAAAARGHHHH
Alright, scratch that, let's add an invisible 20px gap all around the
viewport without measuring as a safe area. Nobody will click in the 20px
gap, right, right?! Everything works great now! Maybe...
Mobile devices, yep, Dialogs are used there as well and usually there is
not a lot of room around those Dialogs so you almost always hit the
"safe area". Should we now try and detect the device people are
using...?
/me takes a deep breath...
Inhales... Exhales...
Alright, time to start thinking again... The outside click with a
"simple" click worked on Menu and Listbox not on the Dialog so this
should be enough right?
WAIT A MINUTE
Remember this piece of code from earlier:
```js
onClick(event) {
event.stopPropagation()
}
```
The click event never ever reaches the `window` so we can't detect the
click outside...
Let's move that code to the `Dialog.Panel` instead of on the `Dialog`
itself, this will make sure that we stop the click event from leaking
if you happen to nest a Dialog in a form and have a submitable
button/input in the `Dialog.Panel`. But if you click outside of the
`Dialog.Panel` the "click" event will bubble to the `window` so that we
can detect a click and check whether it was outside or not.
Time to start cleaning:
- ☑️ Remove all the scrollbar measuring code...
- Closing works on mobile now, no more safe area hack
- ☑️ Remove the pointerdown & mousedown event
- Outside click doesn't fire twice anymore
- ☑️ Use a "simple" click event listener
- We can click the scrollbar and the browser ignores it for us
All issues have been fixed! (Until the next one of course...)
* ensure a `Dialog.Panel` exists
* cleanup unnecessary code
* use capture phase for outside click behaviour
* further improve outside click
We added event.preventDefault() & event.defaultPrevented checks to make
sure that we only handle 1 layer at a time.
E.g.:
```js
<Dialog>
<Menu>
<Menu.Button>Button</Menu.Button>
<Menu.Items>...</Menu.Items>
</Menu>
</Dialog>
```
If you open the Dialog, then open the Menu, pressing `Escape` will close
the Menu but not the Dialog, pressing `Escape` again will close the
Dialog.
Now this is also applied to the outside click behaviour.
If you open the Dialog, then open the Menu, clicking outside will close
the Menu but not the Dialog, outside again will close the Dialog.
* add explicit `enabled` value to the `useOutsideClick` hook
* ensure outside click properly works with Poratl components
Usually this works out of the box, however our Portal components will
render inside the Dialog component "root" to ensure that it is inside
the non-inert tree and is inside the Dialog visually.
This means that the Portal is not in a separate container and
technically outside of the `Dialog.Panel` which means that it will close
when you click on a non-interactive item inside that Portal...
This fixes that and allows all Portal components.
* 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.

* 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" />
```
