Clear selected option in ui-select angular

Note: if we used tagging and tagging-label="false" in that case allow-clear functionality not work.

Custom clear functionality

HTML Code

<ui-select-match placeholder=”Enter table…”>
 <span>{{$select.selected.description || $select.search}}</span>
 <a class=”btn btn-xs btn-link pull-right” ng-click=”clear($event, $select)”><i class=”glyphicon glyphicon-remove”></i></a>
</ui-select-match>

Controller action Code

function clear($event, $select){ 
 //stops click event bubbling
 $event.stopPropagation(); 
 //to allow empty field, in order to force a selection remove the following line
 $select.selected = undefined;
 //reset search query
 $select.search = undefined;
 //focus and open dropdown
 $select.activate();
}

If you are using bootstrap, from design perspective, you could also use a fa-remove icon.

Additionally, from usability perspective, you may want to align the remove icon to the left.

The JS:

<ui-select-match placeholder="Select or find...">
    <button class="clear-btn" ng-click="clear($event)">
        <span class="fa fa-remove"></span>
    </button>
    <span class="clear-btn-offset">{{$select.selected}}</span>
</ui-select-match>

The CSS:

.select2 .clear-btn {
    background: none;
    border: none;
    cursor: pointer;
    padding: 5px 10px;
    position: absolute;
    left: -2px;
    top: 1px;
}

.clear-btn-offset {
    position: absolute;
    left: 25px;
}

On the directive code:

$scope.clear = function($event) {
   $event.stopPropagation();
   // Replace the following line with the proper variable
   $scope.country.selected = undefined;
};

If you are using the select2 theme there is an allow-clear option on the ui-select-match directive that does this for you. You will have the x on the right and you can clear it by clicking it. https://github.com/angular-ui/ui-select/wiki/ui-select-match

Quick example:

<ui-select-match allow-clear="true" placeholder="Select or search a country in the list...">
  <span>{{$select.selected.name}}</span>
</ui-select-match>

This does not currently work using either the bootstrap or selectize theme.

You could add a small X button when you display the selection.

<ui-select-match placeholder="Select or search a country in the list...">
  <span>{{$select.selected.name}}</span>
  <button class="clear" ng-click="clear($event)">X</button>
</ui-select-match>

Then you stop the click event from bubbling up and trigger the open event. And you clear the field by overwriting the selected model.

$scope.clear = function($event) {
   $event.stopPropagation(); 
   $scope.country.selected = undefined;
};
