A Multi-Value Lookup element will appear in the list of elements for a form whenever the object is in a many-to-many relationship with some other object.

For example, the Orders object is in a many-to-many relationship with Tags, by virtue of the junction table between them. So a field called Tags is automatically generated in the element list for the Orders object Form (and vice versa).

From the element list, the field can be dragged into a section of the form, at which point the field type will be displayed: Multi Value Lookup.

Using a Multi Value Lookup

Like other Lookups, the Multi Value Lookup element can be identified by it's magnifying glass icon: Lookupicon.gif. Unlike other Lookups, the GUI gives you a checkbox next to each record and lets you select as many of them as you want.

Sorting a Multi Value Lookup

To control the order in which records appear in the display list:

  1. Visit the Junction Object that lies between the ends of the many-to-many relationship.
  2. In the Junction Object, visit the field that does a Lookup to the object that contains the records you want to sort.
  3. Under Record Selection Information, make selections for the Sort by field and the Sort Order.
