How to populate a tree with a struct with different depth?

I want to import structured signal data from another software and let the user browse and select in a GUI. The imported data contains only the individual name of each signal like so:

plant.tree.fruit.apple

plant.tree.veg.olive.oil

plant.grass.mint

As you see all levels are already separated by dots, but they're all strings and not actual struct.

So far I have successfully turned them into a proper struct, but now I don't know how to populate a tree object with it. The goal is to let the user expand and collapse nodes to find the signal they want in a GUI.

What is a "tree" object?

Answer: loop over the fields at each level of the nested structures. A general solution requires a recursive function.

What have you tried so far?

I have thought of that too, but struggled to create anything concrete. I myself am not familiar with this function either and I couldn't find any examples online with inconstant number of levels.
