I'm trying to use a multiselect listbox within a set of nested listviews to be able to nest my selections by categories.
When fully expanded, I want a multiselect listbox present with all of the items available.
I have this working, however I can't seem to use an automatic height variable with this component meaning I have blank space i don't intend to show.
I'm aiming to replicate something like Looker's field selection box as seen here. I was hoping to avoid simply using text boxes and highlighting them, but I may need to go that route.
See here. I have a multiselectbox here and there are 3 options. The height is configurable manually, but there doesn't seem to be a way to have it autosize based on the number of items in the list.
Additionally, when i add it to a vertically stacked container there is no "fill" option.
