How can I hide Customer portal category

[Dastin_Kuwałek__SoftwarePlant_]

Currently im implementing JIRA Service Desk 3.1.9 and I have created one category for email ticket channel. 

However, customers see this "mail ticket" category on the Customer portal.

How can I hide it?

I was trying javascripting it to hide but it didn't work.

I also thought about modifying SD java classes and recompiling to exclude this category.

I will appreciate help and ideas

Cheers

Some digging and found a way to hide cat by editing SD's template.

Fortunately, in Service Desk 3.3 it's out of the box 

Peace
