I have two overlapped button( They have the same size and position).
And I want when I click the Upper button, the two button all post on button clicked event.
Not really. Buttons are inflexible when it comes to input consumption.
Have a user widget instead - a wrapped border would do. Pass unhandled onMouseDown to reach layers underneath the widget.
But you’ll need to add the other fancy functionality buttons have by default, of course.
I have tried to use a border to and overrided the OnMouseButtonDown Event. However, my click event still cannot pass to underneath widgets.

This is another question from me. Is there any trick in using this way? Or maybe you can give me some advice on debug this blueprint?
