Thank you, Slabbi. I did read the FAQ and saw that multiple selection is not supported with “force loading MooTools 1.3 (use MEIO)” ... did not see this information under the option “do not load MooTools (use MEIO)” which is the one I'm using.
Either way, seems like a step back, no? (Multi selection used to be supported ... or still is if someone's using Joomla 1.5, which they shouldn't ... but no longer is supported for newer versions of Joomla.)
Would you consider adding it back in?
Thank you so much for your support.
