Imagine a very large multiple select box in an create/edit form (more than 5000 option elements...). You need to set/change a value, but this operation requires much time to find the item. I've already done a search script for this monster, which helps me to find all occurrences for any term entered in a special text field representing'em in two groups: already marked and not marked. But may be I need to make a script which could set entered value (or reverse it from selected to non-selected state) too. Just for time saving - if anybody gets a working solution, could you help me? thank you.
