I am using SharePoint Designer 2013 to edit a list page. I am hoping to add a button to the List Item Menu which will run a script, editing the item.
The only options displayed are "Navigate to form", "Initiate workflow", and "Navigate to URL."
I have seen posts referencing the code behind a custom action which is accessible in Visual Studio. Is there any good way of making a Custom Action run a script without having to install and configure Visual Studio?
