    <p>I have the following basic layout:</p> <pre><code>&lt;div id="container"&gt; &lt;div id="div-a"&gt; &lt;ul id="ul-1"&gt; &lt;li id="li-1-1" class="li"&gt;&lt;/li&gt; &lt;li id="li-1-2" class="li"&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; &lt;div id="div-b"&gt; &lt;ul id="ul-2"&gt; &lt;li id="li-2-2" class="li"&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; &lt;div id="div-c"&gt; &lt;ul id="ul-3"&gt; &lt;li id="li-3-1" class="li"&gt;&lt;/li&gt; &lt;li id="li-3-2" class="li"&gt;&lt;/li&gt; &lt;li id="li-3-3" class="li"&gt;&lt;/li&gt; &lt;li id="li-3-4" class="li"&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>What I'm trying to do is, when an input field gets typed into, it initiates a search of the <code>&lt;li&gt;</code> elements. It does a <strong>case insensitive</strong> search on all text contained within the <code>&lt;li&gt;</code> elements. The <code>&lt;li&gt;</code> element will contain html such as images links paragraphs etc. When a match is found it returns the <code>&lt;li&gt;</code> ids e.g. <code>li-1-1,li-2-1</code> etc (whatever is best practice). All this is happening while I type. I plan to get the id's and clone the <code>&lt;li&gt;</code>. But that shouldn't be important at this stage.</p> <p>So far I have the following:</p> <pre><code>$('#my-input').keyup(function(e) { e.stopImmediatePropagation(); var keycode = ( e.keyCode ? e.keyCode : e.which ); if( keycode == 13 ) { //Do something } else { if( $('#my-input').val().length &gt;= 3 ) { //code goes here } } )} </code></pre> <p>What is the best way to go about this. I have looked at contains, filter, looping over all <code>.li</code> elements in various ways etc and had no luck so far. Any help would be much appreciated.</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.
