If you’d like to create a nested ordered list, all you have to do is add some custom CSS in the page you’d like to have the list shown.
CSS Code:
ol { list-style-type: decimal;}
ol ol { list-style-type: upper-alpha;}
ol ol ol {list-style-type: upper-roman;}
ol ol ol ol {list-style-type: lower-alpha;}
ol ol ol ol ol {list-style-type: lower-roman;}
ol ol ol ol ol ol {list-style-type: lower-greek;}
Change the list type to any of the recognized list types.
Results:
