 ### Scrolling long content
 
 When modals become too long for the user's viewport or device, they scroll independent of the page itself. Try the demo below to see what we mean.

+## Sidebar modals
+
+Convert modals into offcanvas sidebar components with the addition of `.modal-left` or `.modal-right`. These classes override the modal's default position, sizing, and transitions to make them appear as offcanvas drawers for content, shopping carts, navigation, and more.
+
+With these two demos, we've removed our optional `.modal-footer`s, but you can add them back. You can also add any custom content within the modal, or change the default appearance, as you need.
+
+### Left modal
+
+Our first demo is for `.modal-left`, which also has a vertical `.nav-pills` component in it. If you include `.fade` on the `.modal`, the modal and backdrop will slowly fade into view instead of sliding into the viewport from offscreen.

 ### Tooltips and popovers
 
 [Tooltips]({{< docsref "/components/tooltips" >}}) and [popovers]({{< docsref "/components/popovers" >}}) can be placed within modals as needed. When modals are closed, any tooltips and popovers within are also automatically dismissed.
