Bootstrap Dropdown Multiselect Not working
<p>Can someone please help me. Dropdown is not working. I was supposed to add the multiselect option but I can't fix this. I've tried rearranging the css and js but it still won't work. Tried placing the scripts and stylesheets that is required and it still won't work. </p>

                buttonWidth: '400px',
                dropRight: true
