The multi-line selector have worked pretty well for the past 10 years but with Lowyat Forum growing, sometimes it is difficult to find the "sub-forum" we would want to search for


To keep the changes minimal, not sure if we can just add a textbox to filter the list of items in multi-select line so that we can quickly select the sub-forum we want to search, implemented at client-side (JavaScript maybe), to filter up to L2 (Forum) / L3 (Sub-Forum) headers showing limited selection.

I also hope for an improvement in search function of our forum, sometimes it's really hard to find a sub topic
