Choose map frame name in ArcPy

Question

In the ArcGIS Pro toolbox, what would be the parameter to set so that we can add a drop-down menu to choose the map frame name?

• PolyGeo: Is this for a Python script tool, a Python Toolbox tool or perhaps a Model tool?

Answer 1

Set the params index number to the parameter for the dropdown. The zero below is for the first parameter.

def initializeParameters(self):
 # Customize parameter properties. 
 # This gets called when the tool is opened.
 aprx = arcpy.mp.ArcGISProject("CURRENT")
 map_list = [mf.name for mf in aprx.listMaps()]
 self.params[0].filter.list = map_list
 return

For map frame elements. The below assumes one Layout in the APRX.

def initializeParameters(self):
 # Customize parameter properties. 
 # This gets called when the tool is opened.
 aprx = arcpy.mp.ArcGISProject("CURRENT")
 lyt = aprx.listLayouts()[0]
 mapf_list = [mf.name for mf in lyt.listElements("MAPFRAME_ELEMENT")]
 self.params[0].filter.list = mapf_list
 return
