Although the queryRuleCustomData widget is not specifically available in Autocomplete, the custom data used by this widget to display a banner is available in the JSON response when a corresponding Rule is triggered.
In this sample response to a query that has triggered a Rule to return custom data, the banner image is available by accessing the userData attribute (
userData.image specifically for the banner).
"title": "YOUR TITLE"
You can customize Autocomplete to display/use this image. This guide to Populating Autocomplete with Sources may be helpful in getting started with your customization. [Note: Customization and implementation guidance is out-of-scope for the Support Team.]
