I have been googling this today and I haven't come up with a decent example. I have grid with a popup editor. I can set the size of the grid, but the controls are all left justified which makes for a very large form that is not very responsive. Are there any examples of a multi-column popup editor? I know a large vertical form won't cut it for the boss. I might be able to convince him popups are not bad if I can do a multi column layout. I tried multiple things...fieldsets...rows...spans all using the bootstrap grid to no avail. Any suggestions? I guess I could use a bootstrap modal instead.
