I had this issue where I want to hover on a drop down icon, be able to go through the options and still close the drop down without attaching a close button. I wanted the overlay to close when my mouse leave but it was still stuck. 

Solution

After linking my dropdown button to the content I wanted using (mouse enter effect), I clicked on the add interaction on the content body, dragged it to the close overlay, changed the ‘on click action’ to ‘mouse leave’
