There is Is Hovered. You can add the elements you want to check to a widget array and check them in a for loop if you’ve got multiple ones.
In my BP I’m just checking whether EnteredWidget is true or not, if it’s false it checks for Is Hovered in another branch, if it’s true it sets EnteredWidget to true. In the next tick the execution flow will go to the true part of the branch and the single widget that was hovered is checked for if it’s hovered or not. In my case I’m not doing anything special if it’s still hovered, I’m just doing an animation with a timer to fade in and fade out the widget. But you could add a DoOnce node to the true branch and set the mouse mode to UI only for example.
