how to hide cobalt menu only to some user-levels?

Did you try all options in Section's MarkUp template? AFAIK, you can turn off any menu element, and even restrict certain elements with usergroup/ACL.

Apart from that, you could restrict the whole menu-block output in a custom markup template.

I understand this, but still th emenu navbar is visible even if the elements are hidden

mhhh... I am afraid I'm not enough skillfull to do that :S, code suggestions :)?

what I want to achieve is to have the navbar with "my menu" element visible to administrators, and hidden for everyone else

oops... I was wrong, the navbar also is being hidden if you are not logged in,

so "my menu" and navbar will still be visible to registered users and superior... but not to guests

Maybe you can add a parameter to a customized markup template to define the user level permission for the menu block.

$this->user->getAuthorisedViewLevels() will help you in the template code to determine the user level.

Try to look into the template code and compare with on of the elements (like template switcher).

It is quite late here already. I might look into it tomorrow (later) for a better suggestion, if you still have problems.

Thank you!

for now I have solved by just enabling only the "my menu" element , as I will not have registered users on this project so I won't have the problem to have to hide that element to them

I have change User menu markup template parameter from Yes/No to access level.

thank you Sergey!
