Prop	Default	Type
`align`		`'start' \| 'center' \| 'end'` The preferred alignment against the trigger. May change when collisions occur.
`alignFlip`		`boolean` Flip alignment when colliding with boundary. May only occur when `prioritizePosition` is true.
`alignOffset`		`number` An offset in pixels from the `start` or `end` alignment options.
`arrowPadding`		`number` The padding between the arrow and the edges of the content. If your content has border-radius, this will prevent it from overflowing the corners.
`as`	`'div'`	`AsTag \| Component` The element or component this component should render as. Can be overwritten by `asChild`.
`asChild`		`boolean` Change the default rendered element for the one passed as a child, merging their props and behavior. Read our Composition guide for more details.
`avoidCollisions`		`boolean` When `true`, overrides the side and align preferences to prevent collisions with boundary edges.
`collisionBoundary`		`Element \| (Element \| null)[] \| null` The element used as the collision boundary. By default this is the viewport, though you can provide additional element(s) to be included in this check.
`collisionPadding`		`number \| Partial<Record<'top' \| 'right' \| 'bottom' \| 'left', number>>` The distance in pixels from the boundary edges where collision detection should occur. Accepts a number (same for all sides), or a partial padding object, for example: { top: 20, left: 20 }.
`disableOutsidePointerEvents`		`boolean` When `true`, hover/focus/click interactions will be disabled on elements outside the `DismissableLayer`. Users will need to click twice on outside elements to interact with them: once to close the `DismissableLayer`, and again to trigger the element.
`disableUpdateOnLayoutShift`		`boolean` Whether to disable the update position for the content when the layout shifted.
`forceMount`		`boolean` Used to force mounting when more control is needed. Useful when controlling animation with Vue animation libraries.
`hideWhenDetached`		`boolean` Whether to hide the content when the trigger becomes fully occluded.
`portal`		`PopoverPortalProps` Props to control the portal wrapped around the content.
`positionStrategy`		`'fixed' \| 'absolute'` The type of CSS position property to use.
`prioritizePosition`		`boolean` Force content to be position within the viewport. Might overlap the reference element, which may not be desired.
`reference`		`ReferenceElement` The custom element or virtual element that will be set as the reference to position the floating element. If provided, it will replace the default anchor element.
`side`		`'top' \| 'right' \| 'bottom' \| 'left'` The preferred side of the trigger to render against when open. Will be reversed when collisions occur and avoidCollisions is enabled.
`sideFlip`		`boolean` Flip to the opposite side when colliding with boundary.
`sideOffset`		`number` The distance in pixels from the trigger.
`sticky`		`'partial' \| 'always'` The sticky behavior on the align axis. `partial` will keep the content in the boundary as long as the trigger is at least partially in the boundary whilst "always" will keep the content in the boundary regardless.
`updatePositionStrategy`		`'always' \| 'optimized'` Strategy to update the position of the floating element on every animation frame.

Emit	Payload
`closeAutoFocus`	`[event: Event]` Event handler called when auto-focusing on close. Can be prevented.
`escapeKeyDown`	`[event: KeyboardEvent]` Event handler called when the escape key is down. Can be prevented.
`focusOutside`	`[event: FocusOutsideEvent]` Event handler called when the focus moves outside of the `DismissableLayer`. Can be prevented.
`interactOutside`	`[event: PointerDownOutsideEvent \| FocusOutsideEvent]` Event handler called when an interaction happens outside the `DismissableLayer`. Specifically, when a `pointerdown` event happens outside or focus moves outside of it. Can be prevented.
`openAutoFocus`	`[event: Event]` Event handler called when auto-focusing on open. Can be prevented.
`pointerDownOutside`	`[event: PointerDownOutsideEvent]` Event handler called when a `pointerdown` event happens outside of the `DismissableLayer`. Can be prevented.
