Searchable

Note: This feature is not built-in but depends on an other plugin. I personnally use the excellent quicksearch library, but you can use whatever library you like.

<select id='custom-headers' multiple='multiple'>
  <option value='elem_1' selected>elem 1</option>
  <option value='elem_2'>elem 2</option>
  <option value='elem_3'>elem 3</option>
  <option value='elem_4' selected>elem 4</option>
  ...
  <option value='elem_100'>elem 100</option>
</select>

$('.searchable').selectMultiple({
  selectableHeader: "<input type='text' class='search-input' autocomplete='off' placeholder='try \"12\"'>",
  afterInit: function(ms){
    var that = this,
        $selectableSearch = that.$selectableUl.prev(),
        selectableSearchString = '#'+that.$container.attr('id')+' .ms-elem-selectable';

    that.qs1 = $selectableSearch.quicksearch(selectableSearchString)
    .on('keydown', function(e){
      if (e.which === 40){
        that.$selectableUl.focus();
        return false;
      }
    });
  },
  afterSelect: function(){
    this.qs1.cache();
  },
  afterDeselect: function(){
    this.qs1.cache();
  }
});
