    <p>I need to apply a jQuery.click to the first level items only. How do I do that?</p> <p>Here is my list:</p> <pre><code>&lt;ul id="adminMenu"&gt; &lt;li id="A"&gt; &lt;h3&gt;&lt;a href=""&gt;Item 1&lt;/a&gt;&lt;/h3&gt; &lt;/li&gt; &lt;li id="B"&gt; &lt;h3&gt;Item 2&lt;/h3&gt; &lt;ul style="display: block;"&gt; &lt;li id="a1"&gt; Sub Item 1 &lt;/li&gt; &lt;li id="a2"&gt; Sub Item 2 &lt;/li&gt; &lt;li id="a3"&gt; Sub Item 3 &lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;li id="C"&gt; &lt;h3&gt;Item 3&lt;/h3&gt; &lt;ul style="display: none;"&gt; &lt;li&gt; Sub Item 4 &lt;/li&gt; &lt;li&gt; Sub Item 5 &lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;/ul&gt; </code></pre> <p>And here is the jQuery</p> <pre><code>jQuery('#adminMenu &gt; li').click(function(){ alert('test'); }); </code></pre> <p><strong>UPDATE</strong><br /> The Alert should <strong>not</strong> fire when I click a Sub Menu item, only when I click list item A, B or C.</p> <p><strong>SOLUTION 1</strong> <br /> This is working code based on Marcels suggestion. </p> <pre><code> jQuery('#adminMenu &gt; li &gt; h3').click(function(e) { var activeUL = jQuery("#adminMenu &gt; li ul:visible"); var activeLI = jQuery("#adminMenu &gt; li ul:visible").parent('li:first'); var clicked = jQuery(this).parent('li:first'); // Close submenu activeUL.hide('fast'); // Open submenu if( activeLI.attr('id') != clicked.attr('id') ) clicked.children('ul').show('fast'); }); </code></pre> <p><strong>SOLUTION 2</strong> <br /> This is working code based on Eyelids suggestion. </p> <pre><code> jQuery('#adminMenu &gt; li').click(function(e) { var clicked = jQuery(e.target); // Ensure we're checking which list item is clicked, // other children should be allowed if(!clicked.is('li') &amp;&amp; clicked.parents('li').length &gt; 0) { // :first ensures we do not select higher level list items clicked = clicked.parents('li:first'); } // If clicked list item is a child of another list item, we'll exit here if(!clicked.is('#adminMenu &gt; li')) { return; } var activeUL = jQuery("#adminMenu &gt; li ul:visible"); var activeLI = jQuery("#adminMenu &gt; li ul:visible").parent('li:first'); // Close submenu activeUL.hide('fast'); // Open submenu if( activeLI.attr('id') != clicked.attr('id') ) clicked.children('ul').show('fast'); }); </code></pre> <p>Thanks guys! I would never have managed this without your help! :)</p>

    1. CORegarding update 2: yes, which is why you'll need to detect if the sub-items were clicked. Click events "bubble", meaning that a click event on a child element is also a click event on its parent elements. The simplest cross-browser* way to stop this bubbling and isolate clicks on parents is to determine if a child element triggered the click event and exit in that case. See my updated answer for implementation of that method. * Note: Non-IE browsers allow "capturing" events (rather than "bubbling"), but since this isn't supported in IE, it's not worth relying on.

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).
