Anyone know how to scroll and collapse a portion of a Column in Compose?

[kevindmoore]

I've tried using the ScrollState, MotionLayout etc. but nothing has really worked so far

[dewildte]

What are you trying to accomplish?

[kevindmoore]

I want something that behaves like a collapsing toolbar, but not inside of a toolbar. Once I scroll up, I want to hide all but the top row

[kevindmoore]

Then expand it out the other way

[dewildte]

Is this item in a list?
Like a LazyColumn?

[kevindmoore]

I am using a Column with Scrollable

[dewildte]

I see.

[dewildte]

My first idea would be to animate the height of the item based on it’s position
from the top of the Column.

[dewildte]

Is the item sticky?
As in does it stay visible even after its collapsed?
Like a LazyListScope.stickyHeader?

[dewildte]

Objects will scroll underneath it?

[kevindmoore]

The top row is always visible

[Abhimanyu]

This seems like a use-case for LazyColumn with sticky header

[dewildte]

Agreed that would get you mostly the way there.
