Multi-Select Control

The Multi-Select control allows you to select one or more items from a list of values by moving items between two list boxes. Add a single item to the Selected Items list box by selecting the item from the Available Items list box and clicking on the arrow icon . Add multiple items by holding down the control (CTRL) key on your keyboard, click each item from the list, and then click the arrow icon.

  1. Create a view.
  2. Drag the control onto the canvas. You can find the control in the Input section of the Toolbox.
  3. Add a data source to your control. To do this, configure the Type under the Data Source of the Properties section.
  4. Configure the rest of the properties as necessary.
  5. Run the view.

If you have a field that can be used in a multi-select list, you can drag the field into the control to bypass step 3 above.

When you click on the ellipsis next to Data Source > Type in the control's Properties, the Configure Data Source page opens. You can use a SmartObject or a static list of values.

The control interacts with other controls through rules. When you bind properties between different controls, you can use the data to populate properties or set values. Use the following examples for when to use the control with other controls through rules:

  • Populate a list control with data: You can populate the control if its data source is a SmartObject
  • Set a control’s properties: You can configure the settable properties of the control with this action
  • Show/Hide: The Visible property allows you to show or hide the control through rules
  • Enable/Disable: The Enabled property allows you to enable or disable the control through rules
  • Data Transfer: You can transfer data from items listed in the context browser to the control
  • You can use either static values or SmartObject list results
  • You must always specify a delimiter because the control saves and loads a delimited list of values
