multiselectable dropdown checkboxes using angular js
<p>I want to design a dropdownlist of checkboxes and make the checkboxes multi-selectable. I have used the below code,but I am unable to make multiple selections as the template refreshes each time I click on a checkbox,please suggest some ideas?</p>

<pre><code>{   &lt;ul class="status-select" class="status-select" ng-if="$index == selectedFilterIndex"&gt;
     &lt;li ng-repeat="DataValue in filter.Data.Value"&gt;
        &lt;input type="checkbox" ng-click="OnDropDownSelectionChanged(filter,DataValue)"&gt;
                        {{DataValue.displayText}}
     &lt;/li&gt;
     &lt;/ul&gt; 
}
</code></pre>
