Guide Section: EASAP GUIs | EASAP Tree: USER INTERFACE Branch

SELECTOR is a very powerful GUI object that allows a User to create and customize a list of items in a table. Below the table are the input objects and modifying BUTTONS: 'Add', 'Update' and 'Delete'. The choices in the list are called USER ITEM's. The items in the list act as DORs and can be referenced by other objects in the EASAP.

SELECTOR
Optional Parameters:
Title:	Text displayed above the list.
Show if:	Logical expression, if TRUE then object shown, if FALSE then object NOT shown.
Enable if:	Logical expression, if TRUE then object enabled, if FALSE then object NOT enabled.
Template Name:	The text prefix of the label of each USER ITEM automatically appended with a digit to form a DOR reference (ie. 'record'→record1, record2,…).

Select Mode:	Type of SELECTOR (LIST ONLY, TABLE ONLY, USER CHOICE).
