Hi,
I am using K2 with J3.2 and the ISIS back-end template.
On the Components > K2 > Items (and Categories) pages (within ISIS) I would like to increase the size of the Categories "drop-down" selection box (and lists) at the page head. The website is large with many categories with some longer names and so there is substantial folding of lines).
I have been unsuccessful in finding the PHP, JQuery or CSS code to controls this. I have identified potential change in the generated HTML using Firebug. My knowledge in these area is limited.

Could someone give me pointers on how to go about this?

Regards,
Robert

I do not think this is something that can be changed in the administrator template without losing all your changes when you update (which you should to 3.3.6 btw).

You can paly around with the script that builds the select boxes (is it a global Joomla! thing, not K2) but I think only the width can be changed harvesthq.github.io/chosen/options.html
