Collapse List Items in Drop Down

We currently have some lists with a large amount of items. It would improve usability if there was an option to collapse list items in a drop down for easier navigation.

I agree. There's currently a limit of like 500 list items before a drop-down switches over to a very unfriendly view for scrolling. Would be nice if there were no limit on how many list members could be in an expandable/collapsible page selector drop-down.
