Feature request: Nested collapsible/expandable lists to the Scroll

[MiMoer]

I'd like to add native support for nested collapsible/expandable lists to the Scroll component, similar to how Engine's Child Layout Group works.

Currently, implementing nested lists with collapsible sections in Druid requires a lot of boilerplate code: manually handling show/hide, recalculating Scroll content size, managing input priority for nested Scrolls, and dealing with layout jumps after expand/collapse.

The main features I'm looking for are:

1. Built-in support for nested Scroll views, with automatic input and stencil handling
2. Native collapsible/expandable components that integrate with Scroll's Grid layout
3. Automatic content size recalculation when sections expand/collapse
4. Optional size constraints (min/max width/height, aspect ratio control) for nested items, similar to the Child Layout options in the attached screenshot

This would greatly simplify building common UI patterns like:

• Settings menus with expandable categories
• Inventory/shop category lists
• Quest logs with expandable task details
• Achievement/collection lists with group sections

Attached screenshot shows the kind of layout controls I'm referring to (Child Layout size overrides, min/max dimensions, aspect ratio).

Hello!
In Panthera, for example, for this use-case, I do a just one scroll + one grid, where I add/remove elements inside it. I’ve once tried nested scroll, and it feels wrong somehow.
But one scroll with elements inside feels easy to implement and maintain.
So you need just to display the left padding for inner elements, but in overall, almost no extra logic fo that.

What do you think about that?
