jquery - Limiting select2 selections even when CTRL is used -


select2 provides option limit selections made user, i.e.:

$('.select2').select2({     maximumselectionlength: 3 });

would allow user select 3 items select2 dropdown.

the issue occurs when user uses ctrl select multiple options - select2 doesn't limit selections made when user selects in fashion.

is there way check selection limit whenever ctrl-selection made? failing can disable ctrl-select functionality? (i couldn't find option in docs..)

see reproduction below. try making more 3 selections first clicking them individually , ctrl-clicking them without closing drop-down.

(function($){    $('.select2').select2({      maximumselectionlength: 3    });  })(jquery);
body{    font-family: sans-serif;  }    .select2{    width: 100%;  }
<link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/css/select2.min.css" rel="stylesheet">  <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/js/select2.full.min.js"></script>    <select class="select2" multiple="multiple">    <option value="1">option 1</option>    <option value="2">option 2</option>    <option value="3">option 3</option>    <option value="4">option 4</option>    <option value="5">option 5</option>    <option value="6">option 6</option>    <option value="7">option 7</option>  </select>

you can listen select2:selecting event , prevent event if 3 items selected.

at moment, preventing user selecting fourth value, may choose display warning message if want.

(function($){    $('.select2').select2({      maximumselectionlength: 3    });        $(".select2").on("select2:selecting", function(e) {      console.log($(this).val(), e.params.args.data);      if($(this).val() && $(this).val().length >= 3) {        e.preventdefault();      }    });  })(jquery);
body{    font-family: sans-serif;  }    .select2{    width: 100%;  }
<link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/css/select2.min.css" rel="stylesheet">  <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/js/select2.full.min.js"></script>    <select class="select2" multiple="multiple">    <option value="1">option 1</option>    <option value="2">option 2</option>    <option value="3">option 3</option>    <option value="4">option 4</option>    <option value="5">option 5</option>    <option value="6">option 6</option>    <option value="7">option 7</option>  </select>
