CMSListMenu and hardcoded list elements?

Easiest thing to do is create a page in the content tree where you want the navigation item to show and that page is just a placeholder and does the redirect to where you want it to go. This way the navigation element shows and you get your redirect.

Hmm but that would create an unnecessary redirect.

How do you specify a redirect within a shell page?

THx

Create the page. On the tabs go to Navigation. Under menu actions, click the radio button "URL redirection" and put in your new page. I use this extensively when migrating systems to newer versions and trees. You get the menu caption you want.

Oh It looks like I would need to use a Repeater to output markup for the Mega Menu I've developed in the prototype......

I should be able to hardcode in an extra LI in the web part HTML envelope field

So your original question asked "...we want certain elements to be represented in the menu that's not part of the CMS site...". The instructions both Charles and I provided will do what you need.

Now on to your next issue, using a CSS List Menu with a mega menu. This can be done, you just need to know how the menu is rendered and the names of the classes that are rendered, then create your styles/classes to wrap around the ones Kentico creates.

The other and better option would be to use a Hierarchical or Universal Viewer. Do not use a repeater with any number of nested repeaters for a mega menu, you will regret it later for performance reasons.
