Grouping Parameters in Python Toolbox of ArcGIS Pro

Question

I am making a Python Toolbox for ArcGIS Pro. The main tool in the toolbox needs to have 5 radio buttons: Users can select any number of options (from 0 to 5).

Is it possible to group or cluster the radio buttons in a single dialog box? Further, since the parameters are optional inputs, is it possible to collapse the dialog box under a drop-down list? Toolbox Code, and ESRI-Interface

Here is the code from the .pyt file, shown in the screenshot above:

# -*- coding: utf-8 -*-
import arcpy
class Toolbox(object):
 def __init__(self):
 """Define the toolbox (the name of the toolbox is the name of the .pyt file)."""
 self.label = "PDF Toolbox"
 self.alias = "Toolbox of PDFs"
 self.tools = [GhostScriptCompress]
class GhostScriptCompress(object):
 def __init__(self):
 """Define the tool (tool name is the name of the class)."""
 self.label = "Ghostscript PDF Compression Tool"
 self.description = "Compresses large PDFs using Ghostscript"
 self.canRunInBackground = False
 def getParameterInfo(self):
 """Define parameter definitions."""
 inPDF = arcpy.Parameter(displayName="Input PDF Document",
 name="outCompiledName",
 datatype="DEFile",
 parameterType="Required",
 direction="Input")
 
 screen = arcpy.Parameter(displayName="Ghostscript 'screen' Compression",
 name="gsCompress_screen",
 datatype="GPBoolean",
 parameterType="Optional",
 direction="Input")
 ebook = arcpy.Parameter(displayName="Ghostscript 'ebook' Compression",
 name="gsCompress_ebook",
 datatype="GPBoolean",
 parameterType="Optional",
 direction="Input")
 printer = arcpy.Parameter(displayName="Ghostscript 'printer' Compression",
 name="gsCompress_printer",
 datatype="GPBoolean",
 parameterType="Optional",
 direction="Input")
 prepress = arcpy.Parameter(displayName="Ghostscript 'prepress' Compression",
 name="gsCompress_prepress",
 datatype="GPBoolean",
 parameterType="Optional",
 direction="Input")
 default = arcpy.Parameter(displayName="Ghostscript 'default' Compression",
 name="gsCompress_default",
 datatype="GPBoolean",
 parameterType="Optional",
 direction="Input")
 
 params = [inPDF, screen, ebook, printer, prepress, default]
 return params
 def isLicensed(self):
 """Set whether tool is licensed to execute."""
 return True
 def updateParameters(self, parameters):
 """Modify the values and properties of parameters before internal validation 
 is performed. This method is called whenever a parameter has been changed."""
 return
 def updateMessages(self, parameters):
 """Modify the messages created by internal validation for each tool
 parameter. This method is called after internal validation."""
 return
 def execute(self, parameters, messages):
 """The source code of the tool."""
 for param in parameters:
 arcpy.AddMessage(f"Parameter ValueAsText: {param.valueAsText}")
 arcpy.AddMessage(f"Parameter Value: {param.value}")
 arcpy.AddMessage(f"Parameter Type: {type(param)}")
 arcpy.AddMessage("-----------------------")
 return

Answer 1

Add a category to the parameters that you want to group. For example

screen = arcpy.Parameter(
 displayName="Ghostscript 'screen' Compression",
 name="gsCompress_screen",
 datatype="GPBoolean",
 parameterType="Optional",
 direction="Input",
 category="Compression",
)
ebook = arcpy.Parameter(
 displayName="Ghostscript 'ebook' Compression",
 name="gsCompress_ebook",
 datatype="GPBoolean",
 parameterType="Optional",
 direction="Input",
 category="Compression",
)

• Keggering: Thanks, @MarkBryant, it was right there in the documentation... pro.arcgis.com/en/pro-app/latest/arcpy/classes/… Thanks!

Answer 2

I used @Mark Bryant's "category" answer/suggestion, coupled with using a "multiValue" parameter-type, instead of a bunch of individual parameter types. Screenshot shows the updated .pyt file, and two ArcGIS Pro views of the tool in the Geoprocessing pane: One collapsed, one expanded.
