I just found this great solution for drag and drop re-ordering in portals:
I found about it through Matt Petrowsky's always helpful tutorials:
Matt mentions that one of the features of the Better Drag Sorting module is achieved through a CSS 'hack'.
Well I just recently went though the incredibly painful process of switching out a classic based theme for one build on the newer themes with proper CSS. As much as I love Charles Delf's amazing solution, I would literally faint if I found out after having implemented it that I had somehow 'screwed up' the CSS and had to re-theme my solution- or worse, simply had a un-fixable file.
If I copy the object from Mr. Delf's module into my solution, can the modified CSS on the object adversely affect my solution?
