I'm currently developing a UI for a tablet application (portrait view)
The client asked us to split the application into two panes, where the left side is a preview pane, and the right side gives the user a gallery of shopping items to "drag and drop" into the cart (i.e. drag the actual item into the cart icon).
As I developed the idea further, I thought about the possibility of including a bottom pane with additional icons (Home, Explore, Profile, Cart) on the left side. But when I tried, it did not look like the user can drag and drop their item into the Cart icon anymore. Furthermore, the whole thing just doesn't look right... so can I ask what the conventions are for this on tablet applications? I know that on mobile apps, the bottom pane needs to cover the whole screen but what about tablet apps, is it the same?
