Re: Multi-select list

[Peter Stavrinides <P....@albourne.com>]

you would need to use some JavaScript, something like this:

var selected = new Array(); 
for (var i = 0; i < ob.options.length; i++) 
  if (ob.options[i].selected) 
    selected.push(ob.options[i].value);

The palette gives you this list already though... so I still can't see what the benefit is in avoiding two lists, its a lot more trouble using a <select.

multiple="true> component??
