A drawer, with a ListView and nested ListView children AND expandable/collapsable - possible?

Widgets & Design

So i have a drawer and there is a list view which is iterating over X groups of filters. Then inside each of those ListViews is a nested view that is showing the options in each group. This works fine.

Ideally I would like each of those groups to be collapsible. So press the group name and the options appear/disappear. Pretty simple I thought - I can use the expanded widget. But I can't it will just crash because the outer draw/column has shrink wrap (and toggling off gives a flutterflow error saying it prevented a crash) and the expandable won't work with shrinkwrap.

So are there other approaches to this that I am not seeing?

Screenshot shows the draw with a handful of options but these can grow and have any number of groups. So if i can allow the user to collapse that would be much clearer for them

What have you tried so far?

Huge combinations of things but no luck so far.

Did you check FlutterFlow's Documentation for this topic?
