hide

hide() provides data to hide the floating element in applicable situations, usually when it's not within the same clipping context as the reference element.

In the above example, the floating element turns red once it has escaped the reference element's clipping context. Once the reference element is hidden, it hides itself.

Usage

import {computePosition, hide} from '@floating-ui/dom';
 
computePosition(referenceEl, floatingEl, {
  middleware: [hide()],
}).then(({middlewareData}) => {
  const {referenceHidden} = middlewareData.hide;
 
  Object.assign(floatingEl.style, {
    visibility: referenceHidden ? 'hidden' : 'visible',
  });
});

Order

hide() should generally be placed at the end of your middleware array.

Options

These are the options you can pass to hide().

interface Options extends DetectOverflowOptions {
  strategy?: 'referenceHidden' | 'escaped';
}

strategy

default: 'referenceHidden'

Specifies the type of hiding strategy to use.

hide({strategy: 'escaped'}); // 'referenceHidden' by default

If you'd like to use multiple strategies, call hide() multiple times in your middleware array with different options.

...detectOverflowOptions

All of detectOverflow's options can be passed. For instance:

hide({padding: 5}); // 0 by default

Data

interface Data {
  referenceHidden?: boolean;
  referenceHiddenOffsets?: SideObject;
  escaped?: boolean;
  escapedOffsets?: SideObject;
}

Depending on the strategy used, these options may exist in the data object.

referenceHidden

Determines whether the reference element is currently not visible on screen for the user.

referenceHiddenOffsets

A side object containing overflow offsets.

escaped

Determines whether the floating element has "escaped" the reference's clipping context and appears fully detached from it.

escapedOffsets

A side object containing overflow offsets.
