How can I dragg an option content provider onto a Dropdown

Hi everybody,

I have database table that contents 4 columns (idProduct, title, details and price)
I created a service connector with adapter that select only titles from the table.
How can I put the list of this titles onto a dropdown in my view with a drag and drop?


right click on the service connectors output document list 'title" and create a new content provider of type “Group of options…” and drag and drop this provider on a dropdown control
