Prefill a Cascading Dropdown in Composer

   Journey Manager (JM) The transaction engine for the platform.  |    Platform Developer  |  All versions This feature is related to all versions.

Manager allows you to update XML data that defines a cascading dropdown in a Composer form from the form properties defined within Manager.

To prefill a cascading dropdown:

1. Open the structure panel in Composer and navigate to the XML data element to adjust the setting for the XML data model bindings in the form before publishing it.



2. Open the properties for the xml data. Navigate to the data model tab and change the binding type to Bound. Note the path as you may need it later.



3. Publish the form to Manager.
4. Navigate to your form in Transaction Manager and click on properties in the Form Versions block for the form you are making these changes to. Here we are going to add a new form property with some modified XML that will be used to update the form in Manager.



5. Click new and fill in the Name and set the data type to String. A new field will become visible; this is where you add the modified xml that will be used to update the form. For this example, another manufacturer was added to the XML from the original example used.

On the right hand side of the page you will see the Targets pane click through the links there to open the path you saw when you changed the bindings for the Xml data in composer it should be something like the picture below.



8. Drag _dropDownXmlData over to the property you created to make the link. Click Save and then save again when it returns to the data config page. Return to the form page. Now when you load the form in Manager, it will reflect the changes made to the XML.
