Sort items inside a listbox

[JR Boulay]

I have some listboxes whose items are filled in by a script and/or via a CSV.

1. I would like items containing "T*T" to appear at the top of the list, sorted alphabetically. (As this word is censored by the forum I wrote it "T * T", you can see it on the screenshot)
2. I would like items containing "ADE" (and not containing "T*T") to appear next, sorted alphabetically.
3. And I would like all the other items to appear after, sorted alphabetically.

See screenshot: white list is the current, yellow list is what I want.

Is it possible?

Sort the items before you add it to the listbox.

[JR Boulay]

I cannot, items are sometimes added in several times by multiple scripts.

[Bernd Alheit]

Then get the items from the listbox, sort the items, and add the items to the listbox.

Thank you.

Hi JR, here's a 30sec script

var oFld = this.getField("List1");
var len = oFld.numItems;
var aItems = [];
for(var i=0;i<len;i++)
     aItems.push([oFld.getItemAt(i,false),oFld.getItemAt(i,true)]);
oFld.setItems(aItems.sort())

Thank you Thom!
