I want to create a custom config with a top node which expands to my different section nodes.
How do I create that top node and add child sections under it? (I have used Thunder to generate each of my current sections I just now need to create that parent node which will hold all the child sections.
Checking the SF docs the help page is currently a 404.
Finally found it
For the child elements add a constructor
public MyElement(ConfigElement parent) : base(parent)
Then ref the child in the parent as
public MyElement Twitter
get return (MyElement)this["My"];
