title: web ui: How to present a large list for multi-select
body: <p>I'm looking for any examples anyone might have seen of how to effectively present a list of items (about 1500 in total) so that multiple items can be selected.</p>
  
  <p>I've seen a couple of similar questions where the answer suggests an auto-complete, which works to select a single item, but that doesn't allow users to select multiple items.</p>
  
  <p>Any suggestions, or especially pointers to web apps that might have a potential solution, would be most appreciated!</p>
