one-time AJAX config to pull in a list

[oakmac]

You should be able to pull in the options for a list using AJAX once and then search those options locally every time that list is referenced.

Use case: you have 1000 options in List 1. Each option references a different List X, which are defined at 1000 different URLs. When the user selects a List X from List 1, you want to hit the URL once, pull in all the options, then search them locally without having to make a new AJAX request for every keystroke.
