As of Twixl Publisher 5.5, publishers are able to add a fully customisable “Hamburger Menu” to their article-based apps. This quick access menu resides in the top right corner of your article-based apps and is managed using a special collection called the Hamburger Menu.
When activating the Hamburger Menu, the well known ‘Gear Menu’ (to access certainly config settings) will be moved to the bottom of the Hamburger Menu (see screenshot).
ACTIVATION AND DEACTIVATION:
When you want to temporarily deactivate the Hamburger Menu, no content will be deleted. The options will just be disabled and the Special Collection will become invisible.
