    text
    <p>Attempting to "disable" a <code>div</code> if its index does not match a clicked <code>a</code> tag:</p> <pre><code>&lt;div data-bind="foreach: slides" class="slidebtns"&gt; &lt;a class="slidebtn" data-bind="text: title, click: $parent.activeIndex.bind($data, $index())" href="#"&gt;&lt;/a&gt; &lt;/div&gt; &lt;div data-bind="foreach: slides"&gt; &lt;div class="screen" data-bind="attr: { id: title }, disable: $parent.activeIndex() !== $index"&gt; &lt;div&gt;test&lt;/div&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>CSS:</p> <pre><code>... .disabled { display: none; } </code></pre> <p>JS:</p> <pre><code>function viewModel() { var self = this; self.activeIndex = ko.observable(0); self.numSlides = ko.observable(3); ... self.slides = ko.computed(function() { var arr = [], n; if (self.numSlides()&lt;6) n = self.numSlides(); else n = 5; for (var i=0; i&lt;n; i++) { arr.push(slideModel(i)); } return arr; }); } function slideModel(n) { var self = this; self.includeImage = ko.observable(true); self.imageSrc = ko.observable('slide_bg1.jpg'); return { title: 'slide'+(n+1) }; } ko.applyBindings(new viewModel()); </code></pre> <p>which does not work. Every <code>div</code> receives a <code>disabled</code> class.</p> <p>As a test I changed the last div to the following to ensure that activeIndex is actually updating properly on click (and it is):</p> <pre><code>&lt;div class="screen" data-bind="attr: { id: title }, css: $root.activeIndex() !== $index ? 'disabled' : ''"&gt; &lt;div data-bind="text: $root.activeIndex()"&gt;&lt;/div&gt; &lt;/div&gt; </code></pre> <p>However, I am too new to KO to figure out how to additionally output the screen $index when the .slidebtn <code>a</code> is clicked so I can actually check if the indices are equal (regardless, they should be equal because there are only 3 of each element type inside a container).</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.
