    <p>The thing is that knockout will always use the value after unwrapping it. If it happens to be an observable, you'll lose those sub-properties. You'll have to rewrap your observable into another object so you don't lose it as you have already found.</p> <p>A nice way you can wrap this up would be to create a function for subscribables (or any of the more derived types) which will do this rewrapping. You can either tack on all individual metadata onto this rewrapped object or pack them into their own separate object. Your code can be elegant again.</p> <pre><code>var buildSelection = function (choices, Parent) { return _(ko.observable()).extend({ // add the metadata to a 'meta' object meta: { choices: choices, availableChoices: ko.computed(function () { if (!Parent) return choices; if (!Parent()) return []; return _(choices).where({ ParentID: Parent().ID }); }) } }); } ko.subscribable.fn.templateData = function (metaName) { return { // access the value through 'value' value: this, // access the metadata through 'meta' meta: this[metaName || 'meta'] // meta property may be overridden }; } </code></pre> <p>Then in your bindings, call this function to create the rewrapped object. Just remember to adjust your bindings in your template.</p> <pre><code>&lt;script id="Selection" type="text/html"&gt; &lt;select data-bind=" options: meta.availableChoices, optionsText: 'Value', value: value, optionsCaption: 'Select One', enable: meta.availableChoices().length "&gt;&lt;/select&gt; &lt;/script&gt; &lt;!-- ko template: { 'name': 'Selection', 'data': Level1.templateData() } --&gt;&lt;!-- /ko --&gt; &lt;!-- ko template: { 'name': 'Selection', 'data': Level2.templateData() } --&gt;&lt;!-- /ko --&gt; &lt;!-- ko template: { 'name': 'Selection', 'data': Level3.templateData() } --&gt;&lt;!-- /ko --&gt; </code></pre> <p><a href="http://jsfiddle.net/jeff1203/UFVYg/9/" rel="nofollow">Updated fiddle</a></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.
