You can split an input on a specific string to get the same field to autocomplete multiple times. One example where you might want to do this is in the case of tags: You have a field that should contain multiple tags, and you want to do an autocomplete after every comma + space (', ').

It's not documented in the rails3-jquery-autocomplete README, but all you need to do is use the 'data-delimiter' attribute like this:

<%= f.label :category_tags %>
<%= f.autocomplete_field :category_tags, autocomplete_category_tag_title_library_assets_path, 'data-delimiter'=>', ' %>

Hopefully this helps you save a little time by allowing you to skip reading the implementation to find this detail.

The example in the post illustrates how to do it. Can you explain a little more about what's going on?

I haven't used this plugin lately, but I'm willing to try to help if I can!
