Is it possible within a Web Map using the Custom Attribute Display (pop up window) to not display fields if the value within the field is NULL? For instance, if your map service/layer has 5 attribute fields, you define the pop up to display all 5 fields but apply a condition to only display the field if it contains values (is NOT NULL). I'm asking because we have a feature with over 75 fields most of which are NULL but can contain values. We would like the pop up to only show the fields with values to reduce the size of the window and avoid the end user having to scroll/search for the important fields.
Thanks in advance,
