Vue Offcanvas Component

Vue alert component allows build hidden sidebars into your project for navigation, shopping carts.

Examples #

Offcanvas components #

Below is an offcanvas example that is shown by default (via :visible="true"). Offcanvas includes support for a header with a close button and an optional body class for some initial padding. We suggest that you include offcanvas headers with dismiss actions whenever possible, or provide an explicit dismiss action.

Placement #

There's no default placement for offcanvas components, so you must add one of the modifier classes below;

• placement="start" places offcanvas on the left of the viewport (shown above)
• placement="end" places offcanvas on the right of the viewport
• placement="top" places offcanvas on the top of the viewport
• placement="bottom" places offcanvas on the bottom of the viewport

Try the top, right, and bottom examples out below.

Accessibility #

Since the offcanvas panel is conceptually a modal dialog, be sure to add aria-labelledby="..."—referencing the offcanvas title—to <COffcanvas>. Note that you don’t need to add role="dialog" since we already add it automatically.
