# inline

The `inline{:.function}` middleware 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(){:js}` may appear "detached" when
measuring over the bounding box.

In the following examples, the `placement{:.objectKey}` is
`'top'{:js}`.

`middleware:{:.objectKey}` `[]{:js}`

<img
  width={692}
  height={256}
  alt="inline disabled"
  src="/inline-disabled.png"
/>

`middleware:{:.objectKey}` `[inline()]{:js}`

<img
  width={692}
  height={256}
  alt="inline enabled"
  src="/inline-enabled.png"
/>

## Usage

```js
import {computePosition, inline} from '@floating-ui/dom';

computePosition(referenceEl, floatingEl, {
  middleware: [inline()],
});
```

### Choosing a rect

By default, `inline(){:js}` infers which of the
`ClientRect{:.class}`s to choose based on the
`placement{:.objectKey}`. 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.

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

referenceEl.addEventListener('mouseenter', onMouseEnter);
```

## Order

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

## Options

```ts
type Options = {
  x: number; // `undefined` by default
  y: number; // `undefined` by default
  padding: number | SideObject; // `2` by default
};
```

### x

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

### y

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

### padding

> **Experimental**

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

This option's configurability is currently experimental and may
be removed by v1. You likely don't need to change the default.
