Has anyone ever had a Switch that wasn't controlled by animation?
```val normalModifier = 0.dp
val expandModifier = 700.dp

val animatedHeight by animateDpAsState(
    targetValue = (if(viewModel.textListSwitch) expandModifier else normalModifier),
    animationSpec = tween(500)
)```
I wrote a height animation of the expanded content, but I found that the Text control inside can be hidden in this way, while the Switch control is still displayed

Can you share how this snippet is used with `Switch`  and maybe a video clip of what the animation looks like now. :slightly_smiling_face:

I seem to have solved the problem and when I use LazyColumn, the problem does not occur

```Column(
    modifier = Modifier
        .padding(8.dp)
        .height(animatedHeight)
        .verticalScroll(rememberScrollState())
)```
what, I also found that if I added .verticalScroll, it also became normal

The Switch has a `requiredSize` defined: <https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/material/material/src/commonMain/kotlin/androidx/compose/material/Switch.kt;l=124?q=switch.kt&amp;ss=androidx%2Fplatform%2Fframeworks%2Fsupport|https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/[…]124?q=switch.kt&amp;ss=androidx%2Fplatform%2Fframeworks%2Fsupport>

As a result, when the parent doesn't have enough space (e.g. 0 height) to accommodate the Switch, it will be centered in the parent. Since the parent doesn't clip, you end up seeing the whole switch.  <https://developer.android.com/jetpack/compose/layout#built-in-modifiers|Here> is an example of the `requiredSize` modifier if you are curious.

For animating expanding/collapsing, I'd recommend  `Modifier.animateContentSize` or `AnimatedVisibility`

You could add `Modifier.animateContentSize` to your column:
```Column(Modifier.animateContentSize()) { 
if(viewModel.textListSwitch) // Show the content only when condition is met
}```
Or put the Column in an `AnimatedVisibility` :
```AnimatedVisibility(visible = viewModel.textListSwitch) { Column(..) {...} }```

by the way, is the navigate animation in Navigation going to be adapted yet? hhahaha

Navigation animation work is being tracked here: <https://issuetracker.google.com/172112072> Please feel free to star for updates. :slightly_smiling_face:
