A horizontal slide out menu with a grid-like thumbnail layout for the submenu. With media query examples for smaller devices.

Demo Code

A simple, horizontal slide out menu with a grid-like thumbnail layout for the submenu. The menu slides out from the top when a main menu item is clicked and the sub-items fade in. When clicking on another item, the height of the submenu will adjust and the content will fade in and out while switching.

Some media query examples show how to make the menu responsive and change the view to a touch-friendly vertically stacked navigation.

  1. Hi, does anyone know how to change the ‘click’ on the main menu list item to a ‘hover’?

    • Hi, have managed to switch to hover, but only problem being getting the menu to hide again on hover out whilst maintaining functionality is proving ellusive *puzzled*

  2. Had some issues with making another button (breadcrumb link) open the submenu as well as the main menu click..

    $('a.LINKCLASS').on('click',function(){ var thisid=$('.MENUBUTTON_class_That_you_want_to_click').parent("li"); // added a class to the menu's <a link> $(thisid).attr('data-open','open'); $(thisid).attr('class','cbp-hsitem-open'); setTimeout( resize_submenuheight, 50 ); // important delay }); function resize_submenuheight(){ var height=$('.click_all_scents').parent("li").children('.cbp-hssubmenu').outerHeight(); $(".cbp-hsmenubg").css("height",height+'px'); }
