With a recent commit[1], we added the scrollerService. However, as a side effect
'Track Visitors' and 'Event Sub-menu' customize menus are not clickable because
they are anchor tags with href=# and the clicks on such anchors are disabled
with scrollerService..
With this task, we take the opportunity to clean up customize menus a bit
because and instead of the anchor tag, now such menus are wrapped within
label (<label>) tags with 'dropdown-item m-0' classes.
Menus are now cleaned and clickable again.
