Hi, I'd like to create a ContextMenu for a ListBox in my app where the callbacks are aware of which item in the ListBox was selected. Is there a way to create the ContextMenu for each item, or can I only do it for the entire ListBox?

If the latter, how could I figure out which item I chose when entering the menu?

@Cyrano Chatziantoniou, for example another list box that dynamically populates depending on the value of the first list box would be a simple one. I think the number of clicks would be the same as your original idea, but maybe you have to move the mouse cursor a little bit farther away...

anyway it's hard to know without knowing more about what you want to accomplish

actually, the context menu itself can be nested, so probably the most obvious way would be just to start with a context menu and use context menus all the way down...but again, depends on what exactly the behavior/outcome is that you are after.
