What?

Adds an icon or link that empties the input element

Resets to empty:    

Resets to "Empty":

Remember that you control the CSS. Make the icon always show by changing the CSS to match the :hover state.

How?

You can set an app-wide reset value using ui.config

<input ng-model="resetModel" ui-reset>
<input ng-model="resetModel" ui-reset=" 'Empty' ">

<script>
    $scope.resetModel = 'Hover over me';
</script>
