Combobox to two panel browser

[ThinkTank]

Hi everyone,

Im getting close to finishing my plugin, that has 4 sample players (layers).
I want to load each layer with sample maps, however the combo box is really not suited for this when you have more than about 50 sample maps. (and its not very organised)

Is there anyone who has managed to create a sample map browser with two panels?

Sorta like this:

Categories:.............|..........Samplemaps:
Pads...........................|..........Dark wave
Leads.........................|..........Deep pad
Drums.......................|..........Dark pad
etc...............................|

Im a bit stuck on this, been searching the forums and have tried following some examples, which is not really working well, or is extremely outdated.

@xxanx Yeah we created a multi-column sample map browser for Mndala (https://www.mntra.io/mndala/)

It's basically one viewport per column, then you need some glue code to show the correct options in viewport 2 based on the selection in viewport 1.

If you want to style it beyond the default viewport appearance then you need to add a panel to each viewport and create your lists with the panel using paint routines/mousecallbacks/etc.

Exactly what I'm looking for. Sweet plugin by the way.
That seems pretty complicated. Its too early for me to program that. I would have to read the documentation 5 times
