Complex views (e.g. list divided into two parts)

Hi there!

I'm trying to write my first plugin for Plex and after two unsuccessful evenings of documentation reading and trial-and-error I was finally able to create a menu structure and some trackobjects for online audio streams. Plex development documentation is really outdated and inconsistent, you never know what's still applicable and how to start.. Luckily there is this community to provide a template! Thanks

 

But to the point - I have my audio streams/tracks divided into a multi-level structure of categories (a tree). Unfortunately the streams can be assigned not only to the leaf categories in the tree but also to parent categories. Which means I would need to display subcategories and tracks in one view, just like folders and files in File Explorer.

I would like to ask - is there a way to show two lists in one view somehow visualy distinguished?

 

Thanks
