Dropdown Select
The Dropdown Select is a pattern that you can apply to other patterns to implement a search functionality or multiple selection in lists. You can use the Dropdown Select UI Pattern when you need an enhanced combo box or list box in forms, as it offers a richer user experience than the list.
How to use the Dropdown Select UI Pattern
-
In Service Studio, in the Toolbox, search for
Dropdown Select.The Dropdown Select widget is displayed.
-
From the Toolbox, drag the Dropdown Select widget into the Main Content area of your application's screen.
-
From the Toolbox, drag the Combo Box widget into the Main Content area of your application's screen, and on the Properties tab, enter a name for the widget. In this example, we enter
ListofEmployees.
-
Right-click your screen name, select Add Local Variable, and enter a name for the new variable. In this example, we enter
SelectedRecord.
-
Select the Combo Box widget, and on the Properties tab, enter the values for the Variable and Source Entity properties. In this example, we select SelectedRecord for the Variable property and drag the Employees entity into the Combo Box widget. This automatically becomes the Source Entity property value.
-
Select the Dropdown Select widget, and on the Properties tab, from the WidgetId drop-down, select the Combo Box widget Id. In this example, we select ListofEmployees.Id.
-
You can change the Dropdown Select's look and feel by setting the (Optional) properties on the Properties tab.
After following these steps and publishing the module, you can test the pattern in your app.
How this pattern behaves depends on the way it is bound.
- If you bind it to a Combo Box widget, Dropdown Select works as a selectable dropdown.
- If you bind it to a List Box, Dropdown Select works as a multi-select dropdown with removable tags.
