```kotlin
fun Modifier.fillMaxWidth(@FloatRange(from = 0.0, to = 1.0) fraction: Float = 1f) =
    this.then(if (fraction == 1f) FillWholeMaxWidth else FillElement.width(fraction))
```


Have the content fill (possibly only partially) the `Constraints.maxWidth` of the incoming
measurement constraints, by setting the `minimum width` and the
`maximum width` to be equal to the `maximum width`
multiplied by `fraction`. Note that, by default, the `fraction` is 1, so the modifier will make
the content fill the whole available width. If the incoming maximum width is
`Constraints.Infinity` this modifier will have no effect.

#### Parameters

| --- | --- |
| fraction | The fraction of the maximum width to use, between `0` and `1`, inclusive. |
