Opening and Closing the Sidebar

Setting the on attribute on one or more elements within the page and setting it's method to toggle will toggle the sidebar when the element is tapped or clicked. Setting the element's method to open or close will open or close the sidebar.Tapping back on the partially-visible main content area closes the sidebar.

Alternatively pressing the escape key on the keyboard will also close the sidebar.


<button class="hamburger" on='tap:sidebar1.toggle'></button>
<button on='tap:sidebar1'>Open</button>
<button on=''>Open</button>
<button on='tap:sidebar1.close'>x</button>



The side attribute may be set to left or right depending upon whether sidebar should open in the left or right side of the page. If a side is not set on the amp-sidebar then it will be inherited from the body tag's dir attribute (ltr => left , rtl => right) and if one does not exist then the side is defaulted to left.


The open attribute is present on the sidebar when it is open.


The only permissible value for the layout attribute in amp-sidebar is nodisplay.

common attributes

This element includes common attributes extended to AMP components.


The amp-sidebar component can be styled with standard CSS.

  • The width of the amp-sidebar may be set to adjust the width of the sidebar between the pre-set min(45px) and max(80vw) values.
  • The height of the amp-sidebar may be set to adjust the height of the sidebar if required. If the height exceeds 100vw then the sidebar will have a vertical scrollbar. The preset height of the sidebar is 100vw and can be overridden in CSS to make it shorter.
  • The current state of the sidebar is exposed via the open attribute that is set on the amp-sidebar tag when the side bar is open on the page.


The amp-sidebar exposes the following actions you can use AMP on-syntax to trigger:

Action Description
open (default) Opens the sidebar
close Closes the sidebar
toggle Toggles the sidebar state


<button on=""> = </button>
<amp-sidebar id="sidebar" layout="nodisplay">
    <li on="tap:sidebar.toggle">Toggle</li>
    <li on="tap:sidebar.close">Close</li>

UX considerations

When using <amp-sidebar>, bear in mind that your users will often view your page on mobile in an AMP viewer, which may display a fixed-position header. In addition, browsers often display their own fixed header at the top of the page. Adding another fixed-position element at the top of the screen would take up a large amount of mobile screen space with content that gives the user no new information.

For this reason, we recommend that affordances to open the sidebar are not placed in a fixed, full-width header.
