    <p>If you take a look at the code below, I'd like to use a text <code>&lt;input&gt;</code> to filter each menu item by multiple ingredients - for example, if the user typed "beef, bacon" into the <code>&lt;input&gt;</code>, the app would return ALL menu items with beef OR bacon as an ingredient.</p> <p>I'm currently trying to do this using ng-filter, and I'm guessing I need to create a custom filter in order to this. Is this the wrong approach?? Is there a way to dynamically chain filters instead?</p> <p>Here's some code which should make sense of my problem -</p> <p><strong>My search model:</strong> <em>- Note: using ng-list to turn string into an array of substrings</em></p> <pre><code>&lt;div ng-init="searchString=[]"&gt; &lt;input type="text" ng-model="searchString" ng-list&gt; &lt;/div&gt; </code></pre> <p><strong>My ng-repeat loop:</strong> <em>- Note: using a custom filter to join each of my ingredient into one string</em></p> <pre><code>&lt;tr ng-repeat="item in menu | filter:{ category : 'Classics' } | filter:{ ingredients : searchString } "&gt; &lt;td class="title"&gt;{{ item.title }}&lt;/td&gt; &lt;td class="ingredients"&gt; {{ item.ingredients | join:', ' }} &lt;/td&gt; &lt;td class="price"&gt;{{ item.price | currency }}&lt;/td&gt; &lt;/tr&gt; </code></pre> <p><strong>My data structure</strong></p> <pre><code>$scope.menu = [ { "title" : "New Yorker", "price" : "4.00", "ingredients" : [ "Salt Beef", "Pickles", "Mustard" ], "category" : "Classics" }, { "title" : "BLT", "price" : "4.00", "ingredients" : [ "Bacon", "Lettuce", "Tomato" ], "category" : "Classics" } ] </code></pre>

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.
