I would like to use Combo Box in my WinForms application to select only one option out of many. This choice affects the whole application and is pretty important, so I don't want to use Menu Strip for this. Therefore Combo Box is the obvious choice.
There is one problem though, I have a two-level hierarchy of these choices and I need to select and display options from the second level. Put simply, I would like to obtain something like this:
Is there a way to do this or something similar easily using WinForms tools? Or some easy way to implement this? I haven't really implemented any visual controls in WinForms before and I don't want to waste a lot of time by learning how to. Thanks for any answer.
