[thelist] ajax dynamic dropdown menu set

Thu Jul 29 05:04:16 CDT 2010

Bob,

Have you looked at the Mootools Clientcide Libraries, they have some neat
widgets for menus and forms ( menu dropdowns, product picker) that may help
with what you a looking for. Originally developed for CNET by Aaron Newton
who now maintains it independently - Aaron is a key Mootools developer.

They look great as well.

Cheers

Simon

Hassan,

Well...er... yes.  Thanks. When I googled this yesterday I grabbed the 
code from one of the promising looking results, not realizing it wasn't 
ajax.  So I went back to the drawing board, did some additional searches 
and found a couple more options.  It does not matter so much whether tis 
ajax or not, so long as it does the job. It was my mistake in not 
deleting the extra doctype stuff when I copied/pasted, but anyhow I have 
an option now that appears to work within Joomla.

Mootools is a set of javascript library stuff that you'll commonly find 
in Joomla installs, sometimes with jQuery as well.  They seem to be 
happily coexisting.
