How to make TreeView for part management

Hello! New Unreal User here!

I am trying to make a TreeView Where it would be a list of parts, that when you click an Item it would be highlighted and play a Lvl Sequence, I tried following but it has been to no avail(Please keep in mind that my experience and knowledge of blueprints is very limited and I don’t understand them that well yet), would appreciate help with the answer or giving directions to where I can find one!

Thank you all in advance!
