[answered] component library subtitle listing - multiparts

Some lib files for the eeschema component selector have multiple subtitles.
I have created my own custom component files and would like subtitles
For example

cpu
   +cpu-a
        item1
        item2 
   +cpu-b
        item1
        item2 
item1
item2
etc

What do I do in the lib component file to trigger this behavior?

I believe the “subtitles” are only for parts with multiple units, there is no way to create a hierarchy of parts.

Doh, ninja’d again!

Oh, I did not notice that - thanks
