Thanks for the reply pankaj,
At the moment this is only a local hosted site. I am starting to convert a very large T3 site to the new T4 setup.
I would expect that the dropdown icon should also be hidden if I hide the sub menus. This was how it was implemented in T3. I think this should also be how T4 operates.
But, most critical is that I need to click more than once on the parent link (with hidden sub menus) for it to activate. Almost as if the first click is buffered (Activating a non-existant sub menu ?).
I will screenshot my setup and post another thread showing step by step what I encounter.
