Move from widget to widget

I’m trying to create a main menu for my game and I want one of the buttons on the menu to open another widget when clicked. How do I do this? (Attempted BP is the bottom row in the image below)


look at my Brick-breaker game template , it can help you , you can see how you can make transition between these (main menu , level selection, ingame hud , game over menu , level completed menu)

It worked. Thank you.
