To make finding forms easier on the forms list screen, forms can be categorized and then filtered on category.
The Mix Forms tab lists all the forms you are subscribed to with Quik!. The far column indicates the category of each form. To change the category of a form, click Edit, select a category from the drop-down menu, and click Save.
To change which options are available in the category drop-down menu, go to Setup > Create > Objects. Find the Mix Form custom object and click the Mix Form link. Find the Category custom field and click the Category link.
In the Values section, click New. Follow the instructions on the screen to add values to the picklist.
