My ComboBox(string) isnt working?

Hey, im super new to the UE, this is like my 2nd or 3rd day using it. I’m watching tutorials and following along. When I place a ComboBox, which if im correct is a dropdown, and run it, there is no hovering image displayed to me and I cant click it and have things drop down. I’ve tried looking up why and watching videos, but everyone doesnt seem to have this issue. I restarted UE4 and it still didnt work. Please help:/

this is some of trivial question, have you added data to be displayed on your ComboBox ? if you can’t click it to open and see options this can be it’s empty because it don’t have any data to show.

You have to populate the combo box with options.
