How to turn off headings from legend using python?

Well, I'm using ArcGIS Pro 2.7 and I want to turn off the 'Headings' from Legend Item. I know how to do it manually, but I need to make a script. Thanks by attention!

Did you look at the CIM class? For example

LegendElement—ArcGIS Pro | Documentation

LegendItem—ArcGIS Pro | Documentation

plus others.

You didn't indicate what you had looked at.

I've ever seen the Documentation above.

If it isn't on the CIM stuff, it may not be available yet.

Hello Wesley,

This can be accomplished using Python CIM Access:

https://pro.arcgis.com/en/pro-app/latest/arcpy/mapping/python-cim-access.htm

Here is a snippet of code that does what you need.

p = arcpy.mp.ArcGISProject('current') lyt = p.listLayouts()[0] #Get the layout's CIM definition lyt_cim = lyt.getDefinition('V2') #Iterate though all layout elements to find the Legend element for elm in lyt_cim.elements: if elm.name == "Legend": #Legend item changes for itm in elm.items: if itm.name == "GreatLakes": #Update visibility itm.showLayerName = True itm.showHeading = False #Set the CIM changes back to the layout lyt.setDefinition(lyt_cim)

There are many Python CIM Access samples located here (including legenditem changes):
