You can use the superuser function (http://codex.wordpress.org/Conditional_Tags#Admin_of_a_Network_.28Multisite.29) if you wanted for this:
function-is-super-admin
However the actual user permissions functions in WP are not true/false condition tests as needed by the menu conditionals because they need parameters and this was not included because of the complexity added. For example to test for user permissions you would use a function like:
<?php
# current_user_can( $capability );
# check if current user is an 'editor'
current_user_can('administrator') # => false
current_user_can('editor') # => true
current_user_can('contributor') # => false
current_user_can('subscriber') # => false
?>
Because there is no way to provide the $capability parameter in the conditionals you can’t use this function directly. Instead, you’ll need to define a function yourself that tests this without any parameters.
This can be done by adding code like this to the “functions.php” file:
<?php
# check if current user is an 'editor'
function current_user_is_editor() {
return current_user_can('editor');
}
?>
Once that is added to “functions.php” you will be able to use the following conditional to your menu:
Show only to editors: function-current-user-is-editor
Show only to non-editors: -function-current-user-is-editor
