Gap Between Footer & Browser Window

Point 3:

Do away with the drop down navbar all together and look at an alternative means of directing visitors around your website on the mobile variant. This is the option I will be going with

A simple, easy to manage option is to create a Mobile Menu Page, similar to the image below. In this example, your hamburger which is sticky on all pages, links to a menu page, which can be a standard Xara Navbar, or individual buttons.



The attached XAR gives you a demo of different options, the menu page and a working drop down menu.

Not sure the issues highlighted in your Points 1 & 2 hold true, but the above menu page option is easy to implement and manage.
