# Focus Trap URL: https://ark-ui.com/docs/utilities/focus-trap Source: https://raw.githubusercontent.com/chakra-ui/ark/refs/heads/main/website/src/content/pages/utilities/focus-trap.mdx Trap focus within a specified container. --- ## Motivation Focus trapping is essential for modal interfaces and other interactive elements that require user attention. The `FocusTrap` component helps maintain accessibility by ensuring keyboard focus remains within a designated container until explicitly released. ## Examples **Example: basic** #### React ```tsx import { FocusTrap } from '@ark-ui/react/focus-trap' import { useState } from 'react' export const Basic = () => { const [trapped, setTrapped] = useState(false) return ( <>
``` ### Autofocus The focus trap respects elements with the `autofocus` attribute. **Example: autofocus** #### React ```tsx import { FocusTrap } from '@ark-ui/react/focus-trap' import { useRef, useState } from 'react' export const Autofocus = () => { const [trapped, setTrapped] = useState(false) const toggle = () => setTrapped((c) => !c) const buttonRef = useRef(null) const getButtonNode = () => { const node = buttonRef.current if (!node) throw new Error('Button not found') return node } return (
{trapped && (
{/* biome-ignore lint/a11y/noAutofocus: intentional */}
)}
) } ``` #### Solid ```tsx import { FocusTrap } from '@ark-ui/solid/focus-trap' import { Show, createSignal } from 'solid-js' export const Autofocus = () => { const [trapped, setTrapped] = createSignal(false) let buttonRef!: HTMLButtonElement return (
) } ``` #### Vue ```vue ``` #### Svelte ```svelte
{#if trapped}
{/if}
``` ### Initial Focus Use the `initialFocus` prop to set the element that should receive initial focus when the trap is activated. **Example: initial-focus** #### React ```tsx import { FocusTrap } from '@ark-ui/react/focus-trap' import { useRef, useState } from 'react' export const InitialFocus = () => { const [trapped, setTrapped] = useState(false) const toggle = () => setTrapped((c) => !c) const inputRef = useRef(null) return (
inputRef.current}>
``` ## API Reference **Component API Reference** #### React **FocusTrap Props:** | Prop | Type | Required | Description | |------|------|----------|-------------| | `asChild` | `boolean` | No | Use the provided child element as the default rendered element, combining their props and behavior. | | `disabled` | `boolean` | No | Whether the focus trap is disabled. | | `fallbackFocus` | `FocusTarget` | No | By default, an error will be thrown if the focus trap contains no elements in its tab order. With this option you can specify a fallback element to programmatically receive focus if no other tabbable elements are found. For example, you may want a popover's `
` to receive focus if the popover's content includes no tabbable elements. *Make sure the fallback element has a negative `tabindex` so it can be programmatically focused. NOTE: If `initialFocus` is `false` (or a function that returns `false`), this function will not be called when the trap is activated, and no element will be initially focused. This function may still be called while the trap is active if things change such that there are no longer any tabbable nodes in the trap. | | `initialFocus` | `VoidFunction | FocusTargetOrFalse` | No | By default, when a focus trap is activated the first element in the focus trap's tab order will receive focus. With this option you can specify a different element to receive that initial focus, or use `false` for no initially focused element at all. NOTE: Setting this option to `false` (or a function that returns `false`) will prevent the `fallbackFocus` option from being used. Setting this option to `undefined` (or a function that returns `undefined`) will result in the default behavior. | | `onActivate` | `VoidFunction` | No | A function that will be called **before** sending focus to the target element upon activation. | | `onDeactivate` | `VoidFunction` | No | A function that will be called **before** sending focus to the trigger element upon deactivation. | | `returnFocusOnDeactivate` | `boolean` | No | Default: `true`. If `false`, when the trap is deactivated, focus will *not* return to the element that had focus before activation. | | `setReturnFocus` | `type ONLY_FOR_FORMAT = | FocusTargetValueOrFalse | ((nodeFocusedBeforeActivation: HTMLElement | SVGElement) => FocusTargetValueOrFalse)` | No | By default, focus trap on deactivation will return to the element that was focused before activation. | #### Solid **FocusTrap Props:** | Prop | Type | Required | Description | |------|------|----------|-------------| | `asChild` | `(props: ParentProps<'div'>) => Element` | No | Use the provided child element as the default rendered element, combining their props and behavior. | | `disabled` | `boolean` | No | Whether the focus trap is disabled. | | `fallbackFocus` | `FocusTarget` | No | By default, an error will be thrown if the focus trap contains no elements in its tab order.
