Thanks that improves a bit I m adding items dynamically to a `ScrollableColumn` and adding ` animateContentSize` makes the column resize more nicely is there an equally easy way to also add fade in out transitions to the individual column elements

Doris Liu · Answer

Re < julioromano> Have you tried for transitioning in out children is a great option too slightly smiling face

Doris Liu · Answer

Re < Mikołaj Kąkol> delay can be achieved with `tween` as such ```tween delayMillis = 100 durationMillis = 200 ```

Thanks But I think I m trying the wrong approach I m replacing a `RecyclerView` which has animations when the list content changes thanks to `DiffUtil` with a `ScrollableColumn` but can t get similar animations when changing content Perhaps that s simply not possible with `ScrollableColumn` In case you are wondering why I m not using `LazyColumn` instead it s because that `RecyclerView` was overkill it managed a relatively small set of items so I thought that view recycling wasn t necessary when rewriting it in Compose but probably the nice animations we get almost for free using `DiffUtil` are simply not possible with `ScrollableColumn`
