From 00cc8c50e36ebac689d1b65dfb09a4357ac7c24d Mon Sep 17 00:00:00 2001 From: Robin Malfait Date: Mon, 15 Mar 2021 12:07:36 +0100 Subject: [PATCH] Add Alert & RadioGroup components (#274) * 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 --- CHANGELOG.md | 2 + packages/@headlessui-react/README.md | 1838 +---------------- .../pages/dialog/dialog-with-alert.tsx | 126 ++ .../pages/radio-group/radio-group.tsx | 101 + .../src/components/alert/README.md | 49 + .../src/components/alert/alert.test.tsx | 31 + .../src/components/alert/alert.tsx | 48 + .../description/description.test.tsx | 108 + .../components/description/description.tsx | 86 + .../src/components/dialog/README.md | 155 ++ .../src/components/dialog/dialog.tsx | 45 +- .../src/components/disclosure/README.md | 81 + .../src/components/disclosure/disclosure.tsx | 10 +- .../src/components/focus-trap/README.md | 64 + .../src/components/keyboard.ts | 2 + .../src/components/label/label.test.tsx | 108 + .../src/components/label/label.tsx | 82 + .../src/components/listbox/README.md | 520 +++++ .../src/components/listbox/listbox.tsx | 2 +- .../src/components/menu/README.md | 406 ++++ .../src/components/menu/menu.tsx | 2 +- .../src/components/popover/README.md | 164 ++ .../src/components/popover/popover.tsx | 26 +- .../src/components/portal/README.md | 45 + .../src/components/portal/portal.test.tsx | 31 +- .../src/components/portal/portal.tsx | 76 +- .../src/components/radio-group/README.md | 89 + .../radio-group/radio-group.test.tsx | 664 ++++++ .../components/radio-group/radio-group.tsx | 333 +++ .../src/components/switch/README.md | 160 ++ .../src/components/switch/switch.tsx | 2 +- .../src/components/transitions/README.md | 308 +++ .../src/components/transitions/transition.tsx | 14 +- .../@headlessui-react/src/hooks/use-flags.ts | 12 + packages/@headlessui-react/src/index.test.ts | 2 + packages/@headlessui-react/src/index.ts | 2 + .../src/internal/portal-force-root.tsx | 26 + .../test-utils/accessibility-assertions.ts | 68 + .../src/test-utils/interactions.ts | 2 + packages/@headlessui-vue/README.md | 1205 +---------- .../src/components/listbox/README.md | 712 +++++++ .../src/components/menu/README.md | 335 +++ .../src/components/switch/README.md | 186 ++ 43 files changed, 5239 insertions(+), 3089 deletions(-) create mode 100644 packages/@headlessui-react/pages/dialog/dialog-with-alert.tsx create mode 100644 packages/@headlessui-react/pages/radio-group/radio-group.tsx create mode 100644 packages/@headlessui-react/src/components/alert/README.md create mode 100644 packages/@headlessui-react/src/components/alert/alert.test.tsx create mode 100644 packages/@headlessui-react/src/components/alert/alert.tsx create mode 100644 packages/@headlessui-react/src/components/description/description.test.tsx create mode 100644 packages/@headlessui-react/src/components/description/description.tsx create mode 100644 packages/@headlessui-react/src/components/dialog/README.md create mode 100644 packages/@headlessui-react/src/components/disclosure/README.md create mode 100644 packages/@headlessui-react/src/components/focus-trap/README.md create mode 100644 packages/@headlessui-react/src/components/label/label.test.tsx create mode 100644 packages/@headlessui-react/src/components/label/label.tsx create mode 100644 packages/@headlessui-react/src/components/listbox/README.md create mode 100644 packages/@headlessui-react/src/components/menu/README.md create mode 100644 packages/@headlessui-react/src/components/popover/README.md create mode 100644 packages/@headlessui-react/src/components/portal/README.md create mode 100644 packages/@headlessui-react/src/components/radio-group/README.md create mode 100644 packages/@headlessui-react/src/components/radio-group/radio-group.test.tsx create mode 100644 packages/@headlessui-react/src/components/radio-group/radio-group.tsx create mode 100644 packages/@headlessui-react/src/components/switch/README.md create mode 100644 packages/@headlessui-react/src/components/transitions/README.md create mode 100644 packages/@headlessui-react/src/hooks/use-flags.ts create mode 100644 packages/@headlessui-react/src/internal/portal-force-root.tsx create mode 100644 packages/@headlessui-vue/src/components/listbox/README.md create mode 100644 packages/@headlessui-vue/src/components/menu/README.md create mode 100644 packages/@headlessui-vue/src/components/switch/README.md diff --git a/CHANGELOG.md b/CHANGELOG.md index 3026e33..b049bc8 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -27,6 +27,8 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 -

Usually you define your duration and what properties you want to transition here, for example `transition-opacity duration-75`. -- **enterFrom**: The starting point to enter from, for example `opacity-0` if something should fade in. -- **enterTo**: The ending point to enter to, for example `opacity-100` after fading in. -- **leave**: Applied the entire time an element is leaving. Usually you define your duration and what properties you want to transition here, for example `transition-opacity duration-75`. -- **leaveFrom**: The starting point to leave from, for example `opacity-100` if something should fade out. -- **leaveTo**: The ending point to leave to, for example `opacity-0` after fading out. - -Here's an example: - -```tsx -import { Transition } from '@headlessui/react' -import { useState } from 'react' - -function MyComponent() { - const [isOpen, setIsOpen] = useState(false) - - return ( - <> - - - I will fade in and out - - - ) -} -``` - -In this example, the transitioning element will take 75ms to enter (that's the `duration-75` class), and will transition the opacity property during that time (that's `transition-opacity`). - -It will start completely transparent before entering (that's `opacity-0` in the `enterFrom` phase), and fade in to completely opaque (`opacity-100`) when finished (that's the `enterTo` phase). - -When the element is being removed (the `leave` phase), it will transition the opacity property, and spend 150ms doing it (`transition-opacity duration-150`). - -It will start as completely opaque (the `opacity-100` in the `leaveFrom` phase), and finish as completely transparent (the `opacity-0` in the `leaveTo` phase). - -All of these props are optional, and will default to just an empty string. - -### Co-ordinating multiple transitions - -Sometimes you need to transition multiple elements with different animations but all based on the same state. For example, say the user clicks a button to open a sidebar that slides over the screen, and you also need to fade-in a background overlay at the same time. - -You can do this by wrapping the related elements with a parent `Transition` component, and wrapping each child that needs its own transition styles with a `Transition.Child` component, which will automatically communicate with the parent `Transition` and inherit the parent's `show` state. - -```tsx -import { Transition } from '@headlessui/react' - -function Sidebar({ isOpen }) { - return ( - - {/* Background overlay */} - - {/* ... */} - - - {/* Sliding sidebar */} - - {/* ... */} - - - ) -} -``` - -The `Transition.Child` component has the exact same API as the `Transition` component, but with no `show` prop, since the `show` value is controlled by the parent. - -Parent `Transition` components will always automatically wait for all children to finish transitioning before unmounting, so you don't need to manage any of that timing yourself. - -### Transitioning on initial mount - -If you want an element to transition the very first time it's rendered, set the `appear` prop to `true`. - -This is useful if you want something to transition in on initial page load, or when its parent is conditionally rendered. -

All you need to do is mark your `Menu.Items` as `static`, wrap it in a ``, and the transition will be applied automatically. - -```jsx -import { Menu, Transition } from '@headlessui/react' - -function MyDropdown() { - return ( - - {({ open }) => ( - <> - More - - {/* Use the Transition + open render prop argument to add transitions. */} - - - {/* ... */} - {/* ... */} - - - - )} - - ) -} -``` - -### Rendering additional content - -The `Menu` component is not limited to rendering only its related subcomponents.

-By default, the `Listbox` and its subcomponents each render a default element that is sensible for that component. - -For example, `Listbox.Label` renders a `label` by default, `Listbox.Button` renders a `button` by default, `Listbox.Options` renders a `ul` and `Listbox.Option` renders a `li` by default. `Listbox` interestingly _does not render an extra element_, and instead renders its children directly by default. - -This is easy to change using the `as` prop, which exists on every component. - -```jsx -import { useState } from 'react' -import { Listbox } from '@headlessui/react' - -const people = [ - { id: 1, name: 'Durward Reynolds' }, -

Instead, the components expose useful information via [scoped slots](https://v3.vuejs.org/guide/component-slots.html#scoped-slots) that you can use to apply the styles you'd like to apply yourself. - -To style the active `ListboxOption` you can read the `active` slot prop, which tells you whether or not that listbox option is the option that is currently focused via the mouse or keyboard. - -To style the selected `ListboxOption` you can read the `selected` slot prop, which tells you whether or not that listbox option is the option that is currently the `value` passed to the `Listbox`. - -You can use this state to conditionally apply whatever active/focus styles you like, for instance a blue background like is typical in most operating systems. For the selected state, you might conditionally render a checkmark next to the seleted option. - -```vue - - - -``` - -### Using a custom label - -By default the `Listbox` will use the button contents as the label for screenreaders. However you can also render a custom `ListboxLabel` which will be automatically linked to the listbox with a generated ID. - -```vue - - - -``` - -### Showing/hiding the listbox - -By default, your `ListboxOptions` instance will be shown/hidden automatically based on the internal `open` state tracked within the `Listbox` component itself. - -```vue - - - -``` - -If you'd rather handle this yourself (perhaps because you need to add an extra wrapper element for one reason or another), you can add a `static` prop to the `ListboxOptions` instance to tell it to always render, and inspect the `open` slot prop provided by the `Listbox` to control which element is shown/hidden yourself. - -```vue - - - -``` - -### Disabling an option - -Use the `disabled` prop to disable a `ListboxOption`. This will make it unselectable via keyboard navigation, and it will be skipped when pressing the up/down arrows. - -```vue - - - -``` - -### Transitions - -To animate the opening/closing of the menu panel, use Vue's built-in `transition` component. All you need to do is wrap your `ListboxOptions` instance in a `` element and the transition will be applied automatically. - -```vue - - - -``` - -### Rendering a different element for a component - -By default, the `Listbox` and its subcomponents each render a default element that is sensible for that component. - -For example, `ListboxLabel` renders a `label` by default, `ListboxButton` renders a `button` by default, `ListboxOptions` renders a `ul` and `ListboxOption` renders a `li` by default. `Listbox` interestingly _does not render an extra element_, and instead renders its children directly by default. - -This is easy to change using the `as` prop, which exists on every component. - -```vue - - - -``` - -To tell an element to render its children directly with no wrapper element, use `as="template"`. -
