I have a web application that currently has menus that drop down 'on hover'. This is obviously an issue on tablets, etc. where there is no hover equivalent.
So, I need to add an 'on click' capability to have the menus drop down, but I'm not sure if I should also leave in the on hover ability, or remove it.
My question is: Should the menus be 'on click' only for consistency or support both on hover/on click to drop down?
edit: the menu is very clearly not the navigation menu at the top of the page, it's more of a control menu for filtering/sorting results on tabular data.
The idea is that hovering over 'Filter by' or 'Columns' drops down a menu that allows you to select which columns are visible, or add filters to the list of results shown.
(come to think of it, maybe it's not as clear as I think)
