Is there a quick way to add a new list to an existing cascading menu web part that occurs on 200+ pages within our website but is not embedded in the master page?
I had wondered whether Site Administrator might be able to replicate a new list where an existing list appears in the same way as it can with duplicating a user’s permissions. Does anyone have suggestions?
I don't know whether Site Admin can do that but a PowerShell or C# app can.
Whether you go PowerShell or C#, the idea is to loop through all site pages that have qCascadingMenu and when you find it change the Configuration property by adding the new list to the existing list.
Please test the solution before running it in the production env. since it can affect your site.
