How to display group header labels in Web Map Contents/Legend Pane

[ScottKaplan1]

Is there a setting in AGOL somewhere to retain or add symbology group headers to the Contents/Legend pane?

For example, on the sample web map I published (see attached), I have the Parks and Forest Header under Public Lands in ArcGIS Pro, but it doesn't carry over to the web map, and I can't find anywhere to add it.

HI,

Have you published the layers to ArcGIS Online? If so, there isn't sub headings. Would renaming the layers in the table of contents get you up and running?
