Configurable list library

Regarding the following post in reference to customizing configurable lists , you mention the method to clone from an existing from URL. Is there a library or such that we can reference? Thank you. 

What library are you referring to? A list of forms with configurable list widget that you can clone? If so, unfortunately, we don't have that one. You can access our Template Gallery or Theme Store to use forms/designs:
