I’m running Drupal 7.28 with Zen 7.x-5.5. In the default setup, there is a region on the right side named “First sidebar” which contains a block named “Navigation”. I have put my navigation links there. When shrinking the width of the browser to see how my site will be rendered on a mobile the navigation block gets positioned at the bottom of the page.
I want the navigation to be at the top in a mobile scenario, ideally with a bootstrap-esque collapsed menu. How can I achieve this?
