Hello,
on our installation the tags are showed for selection (in Add article form in frontend,) ordered by TAG ID. This is not user friendly :(.
Is there any possibility how to show the tags ordered by NAME?
Can it be done somehow in itemform.php?
Thank you very much for feedback!

I'm afraid that this cannot be done without tampering with the K2 core files.

can i add somehow the "ORDER by NAME" for listing of availible tags within itemform.php (which is already modified and is placed in template html folder )?

I don't think editing core files is the best approach here. You can add a simple JS script like this -> jsfiddle.net/stodolaj/De8Ku/ which will continue to work after you have updated K2 (no need for repatching).

thank you! it works good with UL, but with SELECT element there is an issue :(:
the sorting is showing properly within the select list, but after saving some other tags are shown. Looks like the VALUE of SELECT OPTION is somehow not taken into concideration by sorting the select list.):

1. before the sorting the select list:
<option value="3">Vegan</option>

2. after soring of the select list:
<option value="3">APPARTMENTS</option>

systems saves value "3" what is actually "Vegan" and not selected after sorting "Appartments" ...
is it possible to sort with ids of values?

Have you checked this out: stackoverflow.com/questions/12073270/sorting-options-elements-alphabetically-using-jquery ?

Let me know if that did the trick.

going to be interresting :)
