The ordering form field type provides a dropdown list of entries within a specified table along with -First- and -Last-.

• type (mandatory) must be ordering.
• name (mandatory) is the unique name of the field.
• label (mandatory) (translatable) is the field html label.
• table (mandatory) is content table for items needing to be in order.

As an example, see com_banners. In its table definition ##__com_banners it has a catid field which contains the category number of the linked category and also a ordering field which keeps the number of each banner, 1,2,3 etc.

Note If you do not have a catid field then an error is thrown.
