``` ## Usage guidelines - **Drawer extends [Dialog](/components/dialog):** It adds gesture support, snap points, and indent effects. If you don't need these, use Dialog instead. A panel that slides in from the edge of the screen and doesn't need gesture support is a positioned Dialog. ## Anatomy Import the component and assemble its parts: ```svelte ``` Drawer supports swipe gestures to dismiss. Set `swipeDirection` to control which direction dismisses the drawer. `` allows text selection of its children without swipe interference when using a mouse pointer. Add `data-base-ui-swipe-ignore` to a descendant to opt it out of swipe dismissal for all input types. If the element only handles touch drags along one axis, such as a JavaScript carousel, set the value to `x` or `y` so touch drags along the other axis still swipe the drawer. Use `` when a bottom sheet contains form fields and you want Base UI to manage keyboard-aware focus and scroll handling for software keyboards. Drawers without this provider are unaffected. ## Examples ### State By default, Drawer is an uncontrolled component that manages its own state. ```svelte Open Example drawer Close ``` Use `bind:open` and the `onOpenChange` callback if you need to access or control the state of the drawer. Without `bind:`, the drawer manages its own state. ```svelte Open Example drawer Close ``` ### Position Positioning is handled by your styles. `swipeDirection` defaults to `"down"` for bottom sheets. Use `"up"`, `"left"`, or `"right"` for other drawer positions. ```svelte ``` ```svelte Open bottom drawer
Notifications You are all caught up. Good job!
Close
``` ### Nested drawers Use the `[data-nested-drawer-open]` selector and the `--nested-drawers` CSS variable to style drawers when a nested drawer is open. This demo stacks nested drawers using a constant peek so the frontmost drawer stays anchored to the bottom while the ones behind it are scaled down and lifted. It also uses the `--drawer-height` and `--drawer-frontmost-height` CSS variables to handle varying drawer heights. ```svelte Open drawer stack
Account Nested drawers can be styled to stack, while each drawer remains independently focus managed.

``` ### Snap points Use `snapPoints` to snap a bottom sheet drawer to preset heights. Numbers between 0 and 1 represent fractions of the viewport height, and numbers greater than 1 are treated as pixel values. String values support `px` and `rem` units (for example, `'148px'` or `'30rem'`). ```svelte ``` Apply the snap point offset in your styles when using vertical drawers: ```css .DrawerPopup { transform: translateY(calc(var(--drawer-snap-point-offset) + var(--drawer-swipe-movement-y))); } ``` ```svelte Open snap drawer
Snap points
Drag the sheet to snap between a compact peek and a near full-height view.
Close
``` By default, the drawer can skip snap points when swiping quickly. Specify the `snapToSequentialPoints` prop to disable velocity-based skipping so the snap target is determined by drag distance (you can still drag past multiple points). ### Virtual keyboard aware Wrap a bottom sheet in `` to make it react to software keyboards when it contains form controls. When the keyboard opens, the provider scrolls the body to keep the focused field visible. - **Keep the popup frame stable:** place header and footer content outside a plain scrollable body. - **Lift a pinned footer input:** if a footer contains its own input, reserve a footer slot below the scroll area and offset it by `var(--drawer-keyboard-inset, 0px)`. The demo switches the focused footer to `position: fixed` — positioned against the popup, since its `transform` contains fixed descendants — and adds the inset to its bottom padding. - **Always include the `0px` fallback:** the provider only sets `--drawer-keyboard-inset` while the keyboard is aligned, so a bare `var(--drawer-keyboard-inset)` is invalid before the first alignment and after cleanup. ```svelte ``` ```svelte Open keyboard-aware drawer

{#each fields as [label, placeholder] (label)} {/each}
``` ### Indent effect Scale the background down when any drawer opens by wrapping your app in `` and use `` + `` at the top of your tree. Any `` within the provider notifies it when it mounts, which activates the indent parts (they receive `[data-active]` state attributes). ```svelte
Open drawer

Close
``` ### Non-modal Set `modal={false}` to opt out of focus trapping and `disablePointerDismissal` to keep the drawer open on outside clicks. ```svelte Open non-modal drawer Non-modal drawer This drawer does not trap focus and ignores outside clicks. Use the close button or swipe to dismiss it.
Close
``` ### Mobile navigation You can build a full-screen mobile navigation sheet using Drawer parts, including a flick-to-dismiss from the top gesture. ```svelte Open mobile menu ``` ### Swipe to open Place `` along the edge of the viewport to enable swipe-to-open gestures. ```svelte
Swipe here

Swipe from the right edge to open the drawer.

Library Swipe from the edge whenever you want to jump back into your playlists.
Close
``` ### Close confirmation This example shows a nested confirmation dialog that opens if the text entered in the drawer is going to be discarded. To implement this, both the drawer and the confirmation dialog should be controlled. The confirmation dialog may be opened when the `onOpenChange` callback of the drawer receives a request to close while there is text in the textarea. This way, the confirmation is automatically shown when the user clicks the backdrop, presses the Esc key, clicks a close button, or dismisses the drawer with a swipe gesture. Use `eventDetails.cancel()` in `onOpenChange` to prevent the drawer from closing while the confirmation prompt is shown. ```svelte { // Show the close confirmation if there’s text in the textarea if (!open && textareaValue) { eventDetails.cancel(); confirmationOpen = true; return; } if (!open) { // Reset the textarea value textareaValue = ''; } }} > Tweet New tweet
{ event.preventDefault(); // Close the drawer when submitting textareaValue = ''; drawerOpen = false; }} >
Cancel
Discard tweet? Your tweet will be lost.

``` ### Action sheet with separate destructive action This demo builds an action sheet with a grouped list of actions plus a separate destructive action button. ```svelte Open action sheet Profile actions Choose an action for this user.
    {#each ACTIONS as action, index (action)}
  • {#if index === 0} Close action sheet {/if}
    • {/each}
``` ### Detached triggers A drawer can be controlled by a trigger located either inside or outside the `` component. For simple, one-off interactions, place the `` inside ``. However, if defining the drawer's content next to its trigger is not practical, you can use a detached trigger. This involves placing the `` outside of `` and linking them with a `handle` created by the `Drawer.createHandle()` function. The imperative methods on the handle, such as `open()` and `openWithPayload()`, require a `` using the same handle to be mounted. Calls made while no root is attached to the handle — before one mounts, or after it unmounts — are ignored. Each time a root mounts, it starts from fresh state: a call made while no root was attached is not replayed, and no open state carries over from a previous mount. ```svelte Open ... ``` The drawer can render different content depending on which trigger opened it. This is achieved by passing a `payload` to the `` and using the snippet-as-a-child pattern in ``. ```svelte Profile Settings {#snippet children({ payload })} {payload?.title} {/snippet} ``` ### Stacking and animations Use CSS transitions or animations to animate drawer opening, closing, swipe interactions, and nested stacking. The `data-starting-style` attribute is applied when a drawer starts to open, and `data-ending-style` is applied when it starts to close. The `--nested-drawers` CSS variable can be used to determine stack depth. The frontmost drawer has index `0`. ```css .DrawerPopup { --stack-step: 0.05; --stack-scale: calc(1 - (var(--nested-drawers) * var(--stack-step))); transform: translateY(var(--drawer-swipe-movement-y)) scale(var(--stack-scale)); } ``` When stacked drawers have varying heights, use the `--drawer-height` and `--drawer-frontmost-height` variables to keep collapsed drawers aligned with the frontmost one. ```css .DrawerPopup { --bleed: 3rem; --stack-height: max( 0px, calc(var(--drawer-frontmost-height, var(--drawer-height)) - var(--bleed)) ); height: var(--drawer-height, auto); } .DrawerPopup[data-nested-drawer-open] { height: calc(var(--stack-height) + var(--bleed)); overflow: hidden; } ``` The `data-nested-drawer-open` attribute marks drawers behind the frontmost drawer. Use it with `data-nested-drawer-swiping` to dim or hide parent drawer content while keeping it visible during nested swipe interactions. ```css .DrawerContent { transition: opacity 300ms; } .DrawerPopup[data-nested-drawer-open] .DrawerContent { opacity: 0; } .DrawerPopup[data-nested-drawer-open][data-nested-drawer-swiping] .DrawerContent { opacity: 1; } ``` The `--drawer-swipe-movement-x`, `--drawer-swipe-movement-y`, and `--drawer-snap-point-offset` CSS variables can be used to create smooth drag and snap offsets: ```css .DrawerPopup[data-swipe-direction='right'] { transform: translateX(var(--drawer-swipe-movement-x)); } .DrawerPopup[data-swipe-direction='down'] { transform: translateY(calc(var(--drawer-snap-point-offset) + var(--drawer-swipe-movement-y))); } ``` The `data-swipe-direction` attribute can be used with `data-ending-style` to animate directional dismissal: ```css .DrawerPopup[data-ending-style][data-swipe-direction='right'] { transform: translateX(100%); } .DrawerPopup[data-ending-style][data-swipe-direction='down'] { transform: translateY(100%); } ``` Use `--drawer-swipe-progress` to fade the backdrop as the drawer is swiped, and `--drawer-swipe-strength` to scale release transition durations based on swipe velocity. ```css .DrawerBackdrop { --backdrop-opacity: 0.2; opacity: calc(var(--backdrop-opacity) * (1 - var(--drawer-swipe-progress))); } .DrawerPopup[data-ending-style], .DrawerBackdrop[data-ending-style] { transition-duration: calc(var(--drawer-swipe-strength) * 400ms); } .DrawerPopup[data-swiping], .DrawerBackdrop[data-swiping] { transition-duration: 0ms; } ``` ## API reference ### Provider Coordinates page-level drawer UI, such as Drawer.Indent, across the drawers inside it. Doesn't render its own HTML element. ### IndentBackground A background layer placed before Drawer.Indent. Renders a `
` element. `data-active` is present while any drawer inside the nearest Drawer.Provider is open. **Drawer.IndentBackground Props:** | Prop | Type | Default | Description | | :--- | :--- | :------ | :---------- | | render | `Snippet<[props: HTMLAttributes & Record>, state: DrawerIndentBackgroundState, children: Snippet \| undefined]>` | - | | | Attribute | Description | | --------------- | ----------------------------------------------- | | `data-active` | Present when a drawer in the provider is open. | | `data-inactive` | Present when no drawer in the provider is open. | ### Indent A wrapper for the app's main UI. Renders a `
` element. `data-active` is present while any drawer inside the nearest Drawer.Provider is open. The frontmost drawer's swipe progress and height reach it as CSS variables. **Drawer.Indent Props:** | Prop | Type | Default | Description | | :--- | :--- | :------ | :---------- | | render | `Snippet<[props: HTMLAttributes & Record>, state: DrawerIndentState, children: Snippet \| undefined]>` | - | | | Attribute | Description | | --------------- | ----------------------------------------------- | | `data-active` | Present when a drawer in the provider is open. | | `data-inactive` | Present when no drawer in the provider is open. | | CSS variable | Description | | ------------------------- | ------------------------------------------------------- | | `--drawer-swipe-progress` | The frontmost drawer's swipe progress, from `0` to `1`. | | `--drawer-height` | The frontmost drawer's height, while a drawer is open. | ### Root Groups all parts of the drawer. Doesn't render its own HTML element. **Drawer.Root Props:** | Prop | Type | Default | Description | | :--- | :--- | :------ | :---------- | | onOpenChange | `(open: boolean, eventDetails: DrawerChangeEventDetails) => void` | - | Called before the open state changes. Call `eventDetails.cancel()` to veto it. | | handle | `DrawerHandle` | - | Connects detached triggers. Create one with `Drawer.createHandle()`. | | swipeDirection | `DrawerSwipeDirection` | `'down'` | The direction a swipe dismisses the drawer in. | | snapPoints | `DrawerSnapPoint[]` | - | Snap points that size the drawer. Numbers from 0 to 1 are fractions of the viewport height. Larger numbers are pixels. Strings take `px` or `rem` units, such as `'148px'` or `'30rem'`. | | snapToSequentialPoints | `boolean` | `false` | Let the drag distance pick the next snap point, without skipping on velocity. | | snapPoint | `DrawerSnapPoint \| null` | - | The active snap point. Use `bind:snapPoint` to share it with the parent. A value outside `snapPoints` resolves to the closest snap point. | | defaultSnapPoint | `DrawerSnapPoint \| null` | - | The snap point the drawer starts at when `snapPoint` is unset and returns to when it closes. Defaults to the first of `snapPoints`. | | onSnapPointChange | `(snapPoint: DrawerSnapPoint \| null, eventDetails: DrawerSnapPointChangeEventDetails) => void` | - | Called before the snap point changes. Call `eventDetails.cancel()` to veto it. | | children | `Snippet<[{ payload: Payload \| undefined }]>` | - | | | modal | `boolean \| 'trap-focus'` | `true` | `true` traps focus, locks page scroll, and blocks outside pointer interaction. `false` leaves the rest of the page usable. `'trap-focus'` traps focus without locking scroll or outside pointers. | | disablePointerDismissal | `boolean` | `false` | Do not close on outside presses. Non-modal dialogs also stay open when focus moves outside. | | open | `boolean` | `false` | Whether the dialog is open. Use `bind:open` to share it with the parent. A value passed without `bind:` holds until the parent changes it. | | onOpenChangeComplete | `(open: boolean) => void` | - | Called after the open or close animation finishes. | | triggerId | `string \| null` | `null` | Id of the trigger that owns the dialog. Use `bind:triggerId` to share it with the parent. Pass it with an initial `open` to name the trigger the dialog starts from. An id written by a trigger press resets to `null` once the popup unmounts. | ### Trigger A button that opens the drawer. Renders a `
