On click of "select yellow color" button, I want to add yellow to the selected list. Yellow is getting selected, but the dropdown is still showing yellow. In the same way, I want to deselect yellow on click of "deselect yellow color" button. I am able to deselect yellow, but yellow is not appearing in the dropdown. Please help me with this issue. HTML:
<ui-select multiple ng-model="multipleDemo.colors" theme="select2" ng-disabled="disabled" style="width: 300px;">
<ui-select-match placeholder="Select colors...">{{$item}}</ui-select-match>
<ui-select-choices repeat="color in availableColors | filter:$select.search">
{{color}}
</ui-select-choices>
</ui-select>
<p>Selected: {{multipleDemo.colors}}</p>
<input type="button" value="select yellow color" ng-click="selectYellowColor()"/>
<input type="button" value="deselect yellow color" ng-click="deselectYellowColor()"/>
JS:
$scope.availableColors = ['Red','Green','Blue','Yellow','Magenta','Maroon','Umbra','Turquoise'];
$scope.multipleDemo = {};
$scope.multipleDemo.colors = ['Blue','Red'];
$scope.selectYellowColor = function(){
if($scope.multipleDemo.colors.indexOf($scope.availableColors[3]) == -1){
$scope.multipleDemo.colors.push($scope.availableColors[3]);
}
};
$scope.deselectYellowColor = function(){
if($scope.multipleDemo.colors.indexOf($scope.availableColors[3]) != -1){
var index = $scope.multipleDemo.colors.indexOf($scope.availableColors[3]);
$scope.multipleDemo.colors.splice(index, 1);
}
};

UPD: this is an issue in ui-select
component. You can use my solution as a partial workaround until this issue has not been resolved
ui-select
doesn't do filtering of items. It just evaluating your expression in repeat
attribute of ui-select-choices
. If you want to exclude already used value from suggest, you can do it by yourself.
Add extra filter into repeat
<ui-select-choices repeat="color in availableColors | filter:omitSelectedColors | filter:$select.search">
And then define your filtering function:
$scope.omitSelectedColors = function(color) {
return $scope.multipleDemo.colors.indexOf(color) === -1;
}
