As a user, I want to be able to view the column drop down with a click of a mouse
- The user hover on the icon - The down arrow icon is displayed. (Currently, The drop down icon is always visible, instead of being revealed on hover.)
- The user can open the drop down by hovering on the column header and either using mouse right click
- Column drop down should be opening on the right of the column, so that information is not covered.
