A JavaScript library to position floating elements and create interactions for them.

Smart Anchor Positioning

Base UI

A new headless React component library built on top of Floating UI that provides a set of headless floating components (among others) — tooltips, popovers, menus, selects, preview cards, dialogs, toasts, and more.

Interactions for React

Build advanced floating components using Floating UI's React toolkit of components and hooks.

Tooltips

Floating elements that display information related to an anchor element on hover or focus.

Popovers

Floating elements that display an anchored interactive dialog on click.

Select Menus

Floating elements that display a list of options to choose from on click.

Comboboxes

Floating elements that combine an input and a list of searchable options to choose from.

Dropdown Menus

Floating elements that display a list of buttons that perform an action.

Dialogs

Floating windows overlaid on the UI, rendering content underneath them inert.
