[Tkinter] It it possible to make a help file explorer with tkinter?

[Clunk_Head]

I've created an interactive guide using tkinter and I'd like to add a helpfileesque navagation pane to it, as similar to this as possible:

Does anyone have an example or recommendation to create this with tkinter?
It does not need to be fancy, doesn't even need icons
It needs to:
* Have nested entries, and show them as nested
* Either allow for search or have a function for direct navigation focus
* Respond to mouse clicks
* Expand and collapse categories

Any pointer in the right direction would be appreciated.

Edit: Thanks for the move, my bad on the wrong category
