Introduction
Pluggable widgets, such as ComboBox, are identified by their widget ID, not by a namespace reference. This is why the Combo Box cannot be found under the pages namespace when creating the design properties API.
Environment
Combo box (all versions)
Instructions/Procedure
To target the Combo Box, use its widget ID from the package file by following the steps below:
- Locate the ComboBoxWidget.mpk package file.
- Extract the .mpk file (it is a ZIP archive).
- Open the package.xml file from the extracted contents.
- Find the widget ID in the
idattribute of the<widget>element associated with the Combo Box widget. - Use this widget ID as the
widgetTypewhen creating design properties in Model SDK.
The following screenshot shows the id attribute inside the package.xml file for the Combo Box widget:

Outcome
Upon completing these steps, using the Design Properties API to customize the ComboBoxWidget will be possible.
