Scope

Display / Proc.

A selector is used to show all possible child records that could be used to create a relation with the parent record. It will be rendered as a multi-select-box. On clicking on an item inside the selector a new relation is created. The foreign_selector points to a field of the foreign_table that is responsible for providing a selector-box – this field on the foreign_table usually is of type select and also has a foreign_table defined.

In most cases you must assign the field uid_local to the foreign_selector. This field name is used as a convention for the child record of the intermediate table. The automatic generation of MM tables also uses this field name. It depends whether uid_local of the MM table points to the opposite table (of the perspective of your inline field). In case of the opposite direction the field name uid_foreign is usually used.
