Offcanvas Section

You can publish whatever you want in the Offcanvas Section. It can be any module or particle.

By default, the available module positions are offcanvas-a and offcanvas-b but you can add as many module positions as you want from the Layout Manager.

You can also add the hidden-phone module class suffix to your modules so they do not appear in the Offcanvas Section when the site is loaded on a mobile device.

Gantry 5 - Drag & Drop Menu Editor

Gantry 5 features an advanced and user friendly Menu Editor, which augments the core menu with a rich, drag and drop enhanced interface, to easily change the menu's frontend appearance, such as columns.

The Menu Editor panel takes what your CMS' built-in Menu Manager has and enables you to override it. Changes you make in this panel do not in any way affect the way the CMS handles Menu items.
