  <h1>Object as Item Source</h1>
  <p>uiSelect supports providing choices using the <code>(key, value)</code> format, similar to that used by <code>ng-repeat</code></p>

  <h3>Using value for binding</h3>

  <p>Selected: <code>{{ctrl.person.selectedValue}}</code></p>
  <ui-select ng-model="ctrl.person.selectedValue" theme="select2" ng-disabled="ctrl.disabled" style="min-width: 300px;" title="Choose a person">
    <ui-select-match placeholder="Select a person in the list or search his name/age...">{{$select.selected.value.name}}</ui-select-match>
	 <ui-select-choices repeat="person.value as (key, person) in ctrl.peopleObj | filter: { value: { name: $select.search }}">
      <div ng-bind-html="person.value.name | highlight: $select.search"></div>
