thanks but to be honest now I'm even more confused.
why do you need a piece of jquery code in a javascript variable. I sopose
you included the entire jquery library.
Why do you do the ordering with javascript and not with python is there a
special reason for this? I think I just explained the last question by
looking at the code again. The document ready function is executed every
time you add or remove an element from the list?
the javascript variable ordered_values="%s" is filled from the represent
python variable?
And my last question do you implement the multiple select into a form?
Sry for all those questions but I'm still learning and the need for this to
work really pushes my skills and knowledge beyond its limits.
