I am trying to find out what does Joomla Extention uses to list all its extentions??? Is it a component? (what's the name?) Is it a module? (what is the name/title...?)
I like so very mych the advanced search as well as grouping of all extentions?
Are you referring to "
JED - Joomla! Extensions Directory
" if so then that looks like custom code.
You should ask on the Joomla Forum ->
