"Add all" and "Remove all" feature for Angular UI-Select

Using

1) Install via bower

bower install angular-ui-select-add-remove-all --save

2) Add script

<script type="text/javascript" src="components/-somewhere-/ui-select-add-remove-all/ui-select-add-remove-all-directive.js"></script>

3) Add dependency ui.select.addRemoveAll

angular.module('myApp', [
	'ui.select',
	'ui.select.addRemoveAll'
]);

4) Add directive ui-select-add-remove-all

<ui-select multiple
           data-ui-select-add-remove-all
		   data-ng-model="$ctrl.selectedCountry"
	>
	<ui-select-choices repeat="country as country in $ctrl.countries | filter: $select.search">
		{{country}}
	</ui-select-choices>
</ui-select>

5) Manually add items "- ADD ALL -" and "- REMOVE ALL -" to item list in controller.

Note: I'm not able to add this two items automatically into existing component yet. It is reason, why you have to do it manually. :-(

$ctrl.countries = [
	"- ADD ALL -",
	"- REMOVE ALL -",
	"USA",
	"Czech republic",
	"Germany"
];
