I'm trying to implement a drop down menu based on the example at
http://wow.gamepedia.com/Using_UIDropDownMenu.
Looking at the example menu image shown with the section "A Complete Example", is it possible to change the border of the drop down frames?
The example uses a function, "function dropDown:SetValue(newValue)", which appears to be a global function. Must it be global? Just trying to save myself the experimentation headaches in case someone already knows.
Or, perhaps there is a better example than the one on gamepedia. I will say that I am trying to stay away from libraries like Ace's and I'm hoping to eliminate as much global pollution as possible.
