I am having a problem in my application where I would like to have a directive, and inside its template it should conditionally decide whether to recursively render that same directive within it. I have tried to recreate it, and this example is also not working. The directive is not rendered and without errors. I could have made a different mistake in it however.

The problem is a typo: Submenus -> SubMenus
You defined in script.js objects with SubMenus, but you refer in your template to Submenus.
Basically there are 3 problems with your current directive implementation.
lielement withreplace: truewhich is adding one template which hasulagain. So resultant html was incorrect in format, as you can not haveulinsideulagain. Change you directivereplace: truetoreplace: false**OR just remove that option.**menu.Submenusshould bemenu.SubMenusTemplate
