Display field and unique components
Display field in Custom Forms
Each form that you create must have at least 1 display field. Display fields will be the information that will be used to identify the record, so if you link one form to another, the display fields will be the information that appear in your dropdown list, the display field is, to all intents and purposes, the “label” you will use for identifying the record.There can be a combination of different fields used to generate the display field. If for example we’re talking about beneficiaries, you could choose to have both the “First name” and “Last name” fields used. In the example below, you can see that once a field is a “Display field” it is marked with a flag icon.
Unique component in Custom Forms
Unique components allow you to determine a field, or a combination of fields, that should be unique to each record. This will help avoid duplicates and will ensure better data control. To take the example above, you could use First name, Last name and date of birth to concatenate a unique component.
Unique fields are marked with a bookmark icon as the one circled in red below. As you can see, a field can be both a display field and a unique component.
