    <p>I have developed a little javscript widget to turn some nested <code>&lt;ul&gt;</code> blocks into a windows explorer style browser. I have recently learnt about the object literal pattern and decided to give it a go, so the organisation of my code is something like this:</p> <pre><code>var myExplorer = { init : function(settings) { myExplorer.config = { $wrapper : $('#explorerCategories'), $contentHolder : $j('#categoryContent'), loadingImg : '&lt;img src="../images/standard/misc/ajax_loader.gif" alt="loading" class="loading" /&gt;' } // provide for custom configuration via init() if (settings &amp;&amp; typeof(settings) == 'object') { $.extend(myExplorer.config, settings); } // some more code... }, createExpanderLink : function() { // more code }, anotherMethod : function() { // etc } } </code></pre> <p>Then in my page I set up my explorer with:</p> <pre><code>$j(function () { myExplorer.init(); } </code></pre> <p>This all works fine by the way. The problem is when I want to have more then one of these explorer style widgets on the same page. I tried passing in the different settings:</p> <pre><code>$j(function () { // first instance myExplorer.init(); //second instance var settings = { $wrapper : $('#explorerCategories2'), $contentHolder : $j('#categoryContent2') } myExplorer.init(settings); } </code></pre> <p>But this simply overwrites the config vales for the first instance which effectively breaks it. I'm beginning to realise that the object literal pattern isn't the way to go here but I'm not sure what is. Can anyone offer any pointers?</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.
