Unable to contribute code on developer.ww.wp.xz.cn?

Hi all,

So I spent a really long time today learning about how to make a menu walker that would create a menu with Bootstrap classes.

I figure this is probably a common need, so I thought I would contribute my code to the documentation page.

I tried, but the editor strips out or tries to format all of my code, even if I use php or code tags around it.

For example, <div></div> or any other HTML tag isn’t shown, all of my strings are removed, and it’s impossible to tell what the code is supposed to be doing.

How can I contribute my code to help other newcomers?
