You can do that by providing a little javascript snippet that will do exactly that right before we take the screenshot. For that, we recommend using anchor tags so JavaScript knows when to run. So you have pages in the project: ``` https://example.com https://example.com#top-menu ``` And then under the javascript section, you can target the anchor tag ``` if (window.location.hash == '#top-menu') { jQuery('header').find('.header__menu-toggle').click(); } ```
