Hello what I would like in an ArcPro Tool Box is a checking a box make addition arcpy.GetParameterAsText field visible that were not visible before checking the box. Is there a snippets out there please? Thx
Why not specify that the parameter can use multivalues
Parameter—ArcPy classes | Documentation
This can be done in code or through the dialog wizard if you are using custom toolboxes
It will then look like this in the tool dialog
