Hide Custom Field?

[mopa]

I have created a custom field because I want a way to categorize my tickets but it should only be the staff who can see it.

The only way that this fields is easy to go to is by putting it as a staff or customer ticket creation field (this way it will be listed under the "edit" tab for tickets created by the customer and it will be directly from the first page when creation a new staff ticket - which of cause is the nicest way to see it from the first page you are working on)

However to get this working I need the customers NOT to be able to see this and by default the templates will show custom fields for Ticket creation fields.

So is there any way to hide only this specific custom field for the customer (I have other custom fields as well which they have to see)?

Or is there a smooth way of getting a custom field into the actual ticket so no matter who created it it is easily available from the generel tab of a ticket?

Hope you understand my question
And I really hope this is possible somehow because the system really needs a way to categorize support issues.

Create a custom type field from the Admin CP of the software. Manually add this field in the submittickets template and set the type of field to "hidden". That should do the trick.

How am I supposed to do that? Is it described somewhere in details?
