Hi @Anonymous,
You could use concat() function to configure the two dynamic content and "label" in the function.
Like:
concat(items('Apply_to_each')['itk_interests'],'label: ',items('Apply_to_each')['_itk_interests_label'])
The specific expression configuration depends on the specific representation of the two Dynamic content.
You could move your mouse over the dynamic content to see what the specific property name of this Dynamic content is.
Best Regards,
Barry
