                           required="true"
                           close-after-selected="true"

                           suggestions-arr="skillsList1">
    </multiple-autocomplete>

#Getting started

Install "angular-multiple-select" from bower or npm and save it in your package.json or bower.json. For Example :

$ npm install --save angular-multiple-select;
$ bower install --save angular-multiple-select

After installation include its

multiple-select.min.css AND
multiple-select.min.js
<script src="/bower_components/angular-multiple-select/build/multiple-select.min.js"></script>
<link href="/bower_components/angular-multiple-select/build/multiple-select.min.css" rel="stylesheet">

in your html. Then,

Include multipleSelect module in your app: For example :

angular.module('yourModuleName', [
    'multipleSelect'
]);

Now angularMultipleSelect module is injected in your module. You are ready to use it.

You can use it in 2 ways in your form :

  1. If your options list is an array of objects, like :
$scope.optionsList = [
  {id: 1,  name : "Java"},
  {id: 2,  name : "C"},
  {id: 3,  name : "C++"},
  {id: 4,  name : "AngularJs"},
  {id: 5,  name : "JavaScript"}
];
<multiple-autocomplete ng-model="selectedList"
     object-property="name"
     suggestions-arr="optionsList">
</multiple-autocomplete>

Here, in "suggestions-arr" you have to provide the options list from which user can select multiple value. and, "object-property" is which you want to show to user. In above example "name" is the property which i want to show.

"ng-model" will give you an array of selected things. For Ex : If user selects Java & C++, then

ng-model will have
selectedList = [
      {id: 1,  name : "Java"},
      {id: 3,  name : "C++"}
  ]
  1. If your options list is an array of strings, like :
$scope.optionsList = [
  "Java",
  "C",
  "C++",
  "AngularJs",
  "JavaScript"
];
<multiple-autocomplete ng-model="selectedList"
     suggestions-arr="optionsList">
</multiple-autocomplete>

Here, in "suggestions-arr" you have to provide the options list from which user can select multiple value.

"ng-model" will give you an array of selected things. For Ex : If user selects Java & C++, then

ng-model will have
selectedList = [
      "Java",
      "C++"
  ]
  1. To make it required Field in a form
<form name="multipleSelectForm" novalidate>
    <div ng-class="{'has-error' : multipleSelectForm.multipleSelect.$invalid && multipleSelectForm.multipleSelect.$dirty, 'has-success' : !multipleSelectForm.multipleSelect.$invalid && multipleSelectForm.multipleSelect.$dirty}">
        <label>3. Making it Required field in a Form</label>
        <multiple-autocomplete ng-model="skills2" name="multipleSelect" required="true"
                               suggestions-arr="skillsList1">
        </multiple-autocomplete>
        <span ng-show="multipleSelectForm.multipleSelect.$invalid && multipleSelectForm.multipleSelect.$dirty" class="ng-hide">
            <p class="error-msg" ng-show="multipleSelectForm.multipleSelect.$error.required">Please select something from multiple select field</p>
        </span>
    </div>
    <br/>
    <button type="button" class="btn btn-default" ng-click="onSubmit()">Submit Form</button>
</form>
  1. Fetching options list from 3rd party api/url

    You can specify "api-url-option" and you can process response before we capture it. Below is the Example :

        $scope.apiUrlOption = {
            method : "GET",
            responseInterceptor : function (response) {
                /*
                *
                * Process response acc. to your requirement.
                * After processing we are assuming "response.data" as "suggestionsArr".
                *
                * */
            }
        };
     Then in html no need to specify property in "object-property" attribute in directive
    
        <multiple-autocomplete ng-model="skillsFromApi"
                               api-url="{{apiPath}}"
                               suggestions-arr=""
                               api-url-option="apiUrlOption">
        </multiple-autocomplete>

    Part 1. If your Api return an array of strings like :

    [
      "Java",
      "C",
      "C++",
      "AngularJs",
      "JavaScript"
    ]
Then in html no need to specify property in "object-property" attribute in directive
    <multiple-autocomplete ng-model="skillsFromApi"
                           api-url="{{apiPath}}"
                           suggestions-arr="">
    </multiple-autocomplete>
Part 2. If your Api return an array of objects like :
    [
      {id: 1,  name : "Java"},
      {id: 2,  name : "C"},
      {id: 3,  name : "C++"},
      {id: 4,  name : "AngularJs"},
      {id: 5,  name : "JavaScript"}
    ]
Then in html you need to specify property in "object-property" attribute in directive
Here in this case, you have to do like this :
    <multiple-autocomplete ng-model="skillsFromApi"
                            object-property="name"
                           api-url="{{apiPath}}"
                           suggestions-arr="">
    </multiple-autocomplete>
