useFocus

Opens the floating element while the reference element has focus, like CSS :focus.

import {useFocus} from '@floating-ui/react';

To manage focus within the floating element itself, use FloatingFocusManager.

Usage

This Hook returns event handler props.

To use it, pass it the context object returned from useFloating(), and then feed its result into the useInteractions() array. The returned prop getters are then spread onto the elements for rendering.

function App() {
  const [isOpen, setIsOpen] = useState(false);
 
  const {refs, floatingStyles, context} = useFloating({
    open: isOpen,
    onOpenChange: setIsOpen,
  });
 
  const focus = useFocus(context);
 
  const {getReferenceProps, getFloatingProps} = useInteractions([
    focus,
  ]);
 
  return (
    <>
      <div ref={refs.setReference} {...getReferenceProps()}>
        Reference element
      </div>
      {isOpen && (
        <div
          ref={refs.setFloating}
          style={floatingStyles}
          {...getFloatingProps()}
        >
          Floating element
        </div>
      )}
    </>
  );
}
