select2

Did exactly what I needed. There are subtle differences between auto-complete fields. There's the field where you start typing and the cursor jumps to the first entry that matches the typed characters, but the field 1) gives you no feedback as to what you're typing, 2) does it do substring searches and 3) continues to show all the entries in the list regardless of whether they match or not. I don't like those fields. Select2 does it just right - as you type, you are shown only those entries that contain the typed string anywhere in the entry AND it bolds the typed string as you enter. Perfect feedback, ideal for e.g. a knowledgebase search function.

Great little app that does what it says. The default behaviour for multi-select fields in Jira is very clunky when there are 100 or so values in the select list, particularly when you want to add a value to the existing field content. Up until Jira Data Centre 8.2.6 we were running custom JavaScript to alter the behaviour of multi-select fields to mimic the type-ahead and lozenges of the system fields. This stopped working when we upgraded to 8.9.1 and Jira just displayed the JavaScript under the field on the Create screen without executing it. I guess this is due to some security tightening by Atlassian. When we installed select2 and deleted the JavaScript we had the functionality back again. Great job, Pitronote.
