Mouse Hover Problem.

Hi All,

 

Hope everybody is doing well. I have an issue with the hover. As soon as I hover on the values in my ComboBox List and at the end of the last value , hover should retain on  it, but its not happening, Its coming out of the list so I don't see any focus on the list elements. If you have the solution for this please write back to me ASAP. Thanks in advance.
