I am using select2 for multi select and when I select first time , any option , null value from blank option always get selected.
And another problem if I don't use placeholder first option get selected when loaded. 

Here is my code for html(it includes some php):

```
<select class="form-control select2-multiple" name="category_id">
        <option></option>
        @foreach($instrument_category as $key=>$value)
            <option value="{{ $value }}">{{ $value }}</option>
        @endforeach
</select>

```

here is my jquery:

```
$(".select2-multiple").select2({
    'placeholder' : "Select Category",
    'multiple' : true,
    'defaultView': 'dropdown'
});

```

Again problem : blank value get selected when selected for first time.

Screenshot given.
