I have a container object containing multiple charts/pivot tables. I am using 'Drop down at the top' option under appearance as you can see in attached example. When I maximize the container object, drop down button as well as the portion of the container object to the right of the drop down button becomes transparent. It becomes really hard to read the info on transparent button and it just looks unprofessional. How can I make it opaque such that it completely overlaps the underlying objects upon maximize?
