Title: navbar_collapse: hide the navbar-collapse button

On the event of navbar collapse, when no li items are present, the navbar still shows the dropdown button, but with no links. In this commit, I have disabled the button if no items are present.
Attached some screenshots exposing the bug.
Before clicking dropdown button:
