    <p>I followed the following tutorial which is supposed to allow keyboard scrolling and selecting through unordered list items -> <a href="http://www.marcofolio.net/webdesign/advanced_keypress_navigation_with_jquery.html." rel="nofollow">Tutorial</a></p> <p>I'm using it alongside the suggestion box as described -> <a href="http://www.marcofolio.net/webdesign/a_fancy_apple.com-style_search_suggestion.html" rel="nofollow">Suggestion Box</a></p> <p>PLEASE NOTE THAT I FOLLOWED BOTH THESE TUTS TO THE LETTER WITH THE EXCEPTION OF CHANGING ID's and NAMES.</p> <p>It does seem to work (when I key down the hover effect does show), but it immediately disappears after I let go of the key. If I keep the down arrow pressed, it will scroll to the bottom of my list but once the key is released the hover effect disappears immediately. JQuery is by no means my strong suite so I'm not really sure what I'm doing wrong. I'm using the code exactly as described in the tutorial. I've only changed the #menu to #suggestions as this is what my div is named.</p> <p>Here is the code however:</p> <pre><code> var currentSelection = 0; var currentUrl = ''; google.load("jquery", "1.3.1"); google.setOnLoadCallback(function() { // Register keypress events on the whole document $(document).keypress(function(e) { switch(e.keyCode) { // User pressed "up" arrow case 38: navigate('up'); break; // User pressed "down" arrow case 40: navigate('down'); break; // User pressed "enter" case 13: if(currentUrl != '') { window.location = currentUrl; } break; } }); // Add data to let the hover know which index they have for(var i = 0; i &lt; $("#suggestions ul li a").size(); i++) { $("#suggestions ul li a").eq(i).data("number", i); } // Simulote the "hover" effect with the mouse $("#suggestions ul li a").hover( function () { currentSelection = $(this).data("number"); setSelected(currentSelection); }, function() { $("#suggestions ul li a").removeClass("itemhover"); currentUrl = ''; } ); }); function navigate(direction) { // Check if any of the menu items is selected if($("#suggestions ul li .itemhover").size() == 0) { currentSelection = -1; } if(direction == 'up' &amp;&amp; currentSelection != -1) { if(currentSelection != 0) { currentSelection--; } } else if (direction == 'down') { if(currentSelection != $("#suggestions ul li").size() -1) { currentSelection++; } } setSelected(currentSelection); } function setSelected(menuitem) { $("#suggestions ul li a").removeClass("itemhover"); $("#suggestions ul li a").eq(menuitem).addClass("itemhover"); currentUrl = $("#suggestions ul li a").eq(menuitem).attr("href"); } </code></pre> <p>Can anybody perhaps assist me in this matter please?</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
