From the Issue Tracker, click one of the binders. Then, click Admin on the button bar. Click Edit UDFs on the button bar of the Admin menu.

By default, no UDFs are defined for a binder. In order to add UDFs, click the Add New button on the screen.

Type in the Display Name you wish to have appear in the textbox and then choose the Field Type from the drop down list. (For more information on field types, see the General Concepts section).

If you wish to make certain fields mandatory when information is entered either for a new issue or an existing issue, check the field in the Mandatory column. The fields will appear with a "*" next to them in the issue list screen.

You may wish to make certain fields editable by only certain roles in your group. By checking the Administrator Edit box, administrators will be granted edit privileges.

Click Add when finished or press Cancel to return to the main UDFs screen without adding the new UDF.
