Select the Multiple Select List part to add a control that lists elements that a user can select. The user can select multiple elements from the list box. For example, you could use a Multiple Select List part in an order-entry application so that the user can select more than one item for the order.

You can use an ordered collection to add items to the multiple-select list. If you connect the items attribute of the list to an ordered collection, the contents of the list is updated when the ordered collection changes.

You can use any type of item in the multiple-select list. If the items are not strings, you must specify a string to name the items in the Attribute name field on the Multiple Select List - Settings window.

To display the pop-up menu for the part, click with mouse button 2 on the part.

To further define the appearance and function of a part, double-click on it to open the properties window.
