select2 bootstrap sizing issue

Question

I am trying to use a multiple select2 select form in my html with bootstrap. But I'm having issue with sizing, the select2 box is not working with the grid, and it also gurbles the size of next item. The html

<div class="select2-container col-md-11">
    <select class="form-control s2" id="complaint" multiple="multiple" name=
    "complaint[]">
        <option value="bad_breath">
            Bad Breath
        </option>
        <option value="bleeding_gum">
            Bleeding Gum
        </option>
        <option value="swollen_gum">
            Swollen Gum
        </option>
        <option value="gum_pain">
            Gum Pain
        </option>
        <option value="loose_teeth">
            Loose Teeth
        </option>
        <option value="sensitive_teeth">
            Sensitive Teeth
        </option>
        <option value="darkened_teeth">
            Darkened Teeth
        </option>
        <option value="damaged_teeth">
            Damaged Teeth
        </option>
    </select>
</div>

The JS

<script type="text/javascript">
$(".s2").select2({
    closeOnSelect: false
});
$(document).ready(function() {});

First Add in your select box : <select data-width="100%"></select> Add This JS and CSS in you header :

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
    <link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.2/css/select2.min.css" rel="stylesheet" />
