    <p>I have a site template that I am working on that can be seen here:</p> <p><a href="http://www.procardetail.co.uk/" rel="nofollow">http://www.procardetail.co.uk/</a></p> <p>As you can see I have Waypoints in action with a sticky header.</p> <p>Everything works fine when I am scrolling down the page and the navigation links highlight as expected as they encounter the anchors on the page.</p> <p>However when scrolling up, the functionality of highlighting the links does not work.</p> <p>The javascript I am using looks like this:</p> <pre><code>$(function() { // Do our DOM lookups beforehand var nav_container = $("#navs"); var nav = $("nav"); var top_spacing = 15; var waypoint_offset = 50; nav_container.waypoint({ handler: function(event, direction) { if (direction == 'down') { nav_container.css({ 'height':nav.outerHeight() }); nav.stop().addClass("sticky").css("top",-nav.outerHeight()).animate({"top":top_spacing}); } else { nav_container.css({ 'height':'auto' }); nav.stop().removeClass("sticky").css("top",nav.outerHeight()+waypoint_offset).animate({"top":""}); } }, offset: function() { return -nav.outerHeight()-waypoint_offset; } }); var sections = $("section"); var navigation_links = $("nav a"); sections.waypoint({ handler: function(event, direction) { var active_section; active_section = $(this); if (direction === "up") active_section = active_section.prev(); var active_link = $('nav a[href="#' + active_section.attr("id") + '"]'); navigation_links.removeClass("selected"); active_link.addClass("selected"); }, offset: '25%' }) navigation_links.click( function(event) { $.scrollTo( $(this).attr("href"), { duration: 100, offset: { 'left':0, 'top':-0.15*$(window).height() } } ); }); </code></pre> <p>});</p> <p>Is anyone able to shed some light on why this is happening?</p> <p>Thanks for your time and help in advance.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
