drop-down menu

Hello guys,

I recently started a game development project, I am doing the design of the interface.
for interfacing I need a drop down menu.

In fact, I want to create setting menu.

The drop down menu used to select between 2 solutions. FullScreen Mode or windowed mode.
But I do not know how to install the drop down menu.

thank you for your patience and your help

I am assuming you are using Unreal Motion Graphics for your UI? If so, there is exactly that. Take a look at ALLthe options on the left panel while in UMG editor, you will find it.
Here is UMG WIP video that shows a drop down menu in action!
