Question about hovering zone

Hi, I have a question and i cannot find the answer to it anywhere. I am creating a side menu that pop out when i am hovering… I managed to di it BUT the hovering zone is still the previous small menu and not the new one that pop out. So i cannot go and select the item in the new menu because when i leave the small hovering zone, the menu close back… I tried an overlay, i do not see any option to define a new zone for the hover to keep it open. What do I do wrong?

There are multiple ways to make this, but the most straight forward way is just to change “Hover” to “Mouse enter”.
