Mobile sidebar menu elements

To enable or disable mobile sidebar menu elements, navigate to Theme Options → Header → Header Mobile, scroll down to the "Menu Elements" section and click the eye icon of the desired/undesired element.

When the sidebar menu is open you can see the changes live updating.

In case you see "WooCommerce not found", in the sidebar, then WooCommerce is not installed or activated at this point, deactivate the "Account" element, to get rid of it in case you do not wish to install or activate WooCommerce. The "Account" element needs WooCommerce to function and is enabled by default.
