DropDownByKey requires some lines of code! There is one exception: use a datatype (datalement) attached to a domain with fixed values. The fixed values, defined in the dictionary, will populate the dropdown. "It's magic".

DropDownByIndex uses a different approach: a dedicated node in the Context (easy to populate via Supply Function).

Hi Madhu,

Without programaticaly we can't achieve this functionality. As Sascha suggested we need to insert a blank key, value in the table which we bind to the node's attribute.

Best regards,
