OverlayPositionerProps #

altBoundary

Whether to check the alternate elementContext’s boundary. Please see https://floating-ui.com/docs/detectoverflow#altboundary for more information.

Type: boolean

Default: false

autoUpdate

Options to activate auto-update listeners

Type: boolean | AutoUpdateOptions

See

https://floating-ui.com/docs/autoUpdate

boundary

Describes the clipping element(s) or area that overflow will be checked relative to. Please see https://floating-ui.com/docs/detectoverflow#boundary for more information.

Type: Boundary

Default: 'clippingAncestors'

elementContext

The element that will be used to check for overflow. Please see https://floating-ui.com/docs/detectoverflow#elementcontext for more information.

Type: ElementContext

fitViewport

Whether to constrain the floating element's width and height to not exceed the viewport.

Type: boolean

Default: false

flip

Whether to flip the placement in order to keep it in view when the preferred placement(s) will overflow the clipping boundary. You can also provide an array of placements to try sequentially if the preferred placement does not fit.

Type: boolean | Placement[]

Default: true

hide

Whether to hide the floating element when the reference element or the floating element is fully clipped.

Type: boolean

Default: false

hoist

Whether to use the browser Popover API to place the floating element on top of other page content. When enabled, the floating element won't be clipped by an ancestor. This provides a similar result to React's <Portals> or Vue's <Teleport>.

Type: boolean

Default: true

inline

Whether to improve positioning for inline reference elements that span over multiple lines.

Type: boolean

Default: false

offset

The distance between the reference and floating element.

Type: OffsetOptions

Type: number

Default: 4

overlap

Whether the floating element can overlap the reference element to keep it in view.

Type: boolean

Default: false

placement

The initial placement of the floating element

Type: Placement

Type: boolean

Default: false

sameWidth

Whether to constrain the floating element's width so that it matches the reference element.

Type: boolean

Default: false

shift

Whether the floating element should shift to keep it in view.

Type: boolean

Default: true

strategy

The strategy to use for positioning

Type: "fixed" | "absolute"

Default: "absolute"

Type: boolean

Default: false
