Q:

html javascript select option control with huge number of elements (like 10K)

I have two  controls with huge nubmer of elements and I move elements from one to another with arrows (built as a single control).
however moving elements from one select to another takes lot of time (i have 10K elements)
i want to know if there is already a best practice or a ready made control that can do that and fast.
thanks

A:

You may ant to have a look at jQuery UI MultiSelect plugin.
What it does is transform a html select multiple into exactly what you want.
I do not know how well it works with very big lists, though. The nice thing is that it will still work if javascript is disabled.
