I have built a script tool in ArcGIS Pro and I would like to set up one parameter as a drop down menu (the options in the drop down menu should be all the attribute values of one of the map layers).
I can't seem to find the right 'Data type' to pick up. If I choose 'Layer' as 'Data Type' and I run the tool I get a drop down menu with all map layers. I'm looking for something similar but specific to a layer field. If I choose 'field' in 'Data Type' and I run the tool absolutely nothing happens. What is this 'field' referring to? How could I achieve what I'm looking for?
