Read the original Bootstrap documentation on offcanvas here.
The offcanvas block allows you to add hidden sidebars to your page that can be displayed at the click of a button. By adding the offcanvas block you gain access to additional blocks: Offcanvas Header and Offcanvas Body. Both of these blocks have limited options available – they both provide the flexibility to add whatever content you like into them and only have the advanced settings which are the same as the parent offcanvas block .Toggle Offcanvas
In order to get the offcanvas block to function there are a few steps you need to take:
An example of this would be to add the HTML anchor attribute to the offcanvas of my-offcanvas you would then need to add a link or button that links to #my-offcanvas. The rest will be taken care of for you.
The offcanvas block has the following options:
The backdrop option allows you to control whether or not a background overlay should be included with the offcanvas. By default the backdrop will be visible. There are two options available:
The scrollable option allows you to control whether the page body should be scrollable when the sidebar is visible. By default the body is not scrollable. There are two options available:
The placement option allows you to control where abouts on the page the sidebar should be positioned. There are four options available:
.offcanvas-startclass and positions the sidebar to the left of the page
.offcanvas-endclass and positions the sidebar to the right of the page
.offcanvas-topclass and positions the sidebar to the top of the page
.offcanvas-endclass and positions the sidebar to the bottom of the page
Blocks tend to have a large number of settings along with different settings for each device size. You may get to the point where you have changed lots of settings and want to revert them back to the default. This can be time consuming and difficult to remember which settings have been changed to we have supplied three buttons that make this a piece of cake. Simply click the relevant button to reset your settings.
The HTML anchor option allows you to set an ID on the current block. This is useful when you wish to link to a specific area on a page.
The additional class(es) option lets you add any other classes to the block. This is really useful as it allows you to utilise all of the Bootstrap utility classes to quickly apply styles and add more advanced customisations. A few examples of this would be to align all inner content by adding the
text-end classes. You also have the ability to quickly search all of the available Bootstrap classes. To search Bootstrap classes open the Add Bootstrap class select box. You can filter the results by typing in the available search field. When you select an option it will automatically be added to your class list.
