Hi Muhammad,



You should call method setMultiSelect in the section on the init function:



 

define("ContactSectionV2", ["css!UsrContactSectionV2CSS"], function() {
	return {
		entitySchemaName: "Contact",
		attributes: {},
		details: /**SCHEMA_DETAILS*/{}/**SCHEMA_DETAILS*/,
		diff: /**SCHEMA_DIFF*/[]/**SCHEMA_DIFF*/,
		methods: {
			init: function() {
				this.setMultiSelect();
				this.callParent(arguments);
			}
		}
	};
});

Dmytro Smishchenko,

Thank you for suggestion, I checked its working but there is a issue.

Issue: when I click on record the form is appeared, then I clicked on "Close" button and return to listview then checkboxes are not showing.
