inline

inline() provides improved positioning for inline reference elements that span over multiple lines, such as hyperlinks or range selections.

This is useful as the default positioning using getBoundingClientRect() may appear "detached" when measuring over the bounding box.

In the following examples, the placement is 'top'.

Usage

import {computePosition, inline} from '@floating-ui/dom';
 
computePosition(referenceEl, floatingEl, {
  middleware: [inline()],
});

Choosing a rect

By default, inline() infers which of the ClientRects to choose based on the placement. However, you may want a different rect to be chosen.

For instance, if the user hovered over the last client rect, you likely want the floating element to be placed there. This logic is only applied when the reference element's rects are disjoined.

function onMouseEnter({clientX, clientY}) {
  computePosition(referenceEl, floatingEl, {
    middleware: [inline({x: clientX, y: clientY})],
  }).then(({x, y}) => {
    // ...
  });
}
 
referenceEl.addEventListener('mouseenter', onMouseEnter);

Order

inline() should generally be placed toward the beginning of your middleware array, before flip() (if used).

Options

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

interface Options {
  x?: number;
  y?: number;
  padding?: number | SideObject;
}

x

default: undefined

This is the viewport-relative (client) x-axis coordinate which can be passed in to choose a rect.

y

default: undefined

This is the viewport-relative (client) y-axis coordinate which can be passed in to choose a rect.

padding

default: 2

This describes the padding around a disjoined rect when choosing it.
