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.
