Sorry I guess maybe I assumed by it being in the development forum it would fill in the blanks. My apologies.
Say I developed a new theme, I have a new template in that theme called Middle. Now I am developing an addon, I have a addon option for my addon for the user to put in a template they'd like the addon to show up on. But my new template has 3 Divs to divide up the template. I would love the addon to be in the 2nd Div statement, and CSS seems like the best way to do this. But by default, it will insert before the DIV statements. I'd like to give an option somehow for users to position it within their existing or new templates. What would be the best way to go about this?
