You may want to use

https://cdnjs.cloudflare.com/ajax/libs/bootstrap-multiselect/0.9.13/js/bootstrap-multiselect.min.js

Add this CSS to break the selection

.multiselect-selected-text{
  display: inline-block;
  max-width: 100%;
  word-break: break-all;
  white-space: normal;
}

SNIPPET

 $(document).ready(function() { $('#example-getting-started').multiselect({ includeSelectAllOption: true, enableFiltering: true, buttonText: function(options, select) { if (options.length == 0) { return 'Select Groups'; } else { var selected = ''; options.each(function() { selected += $(this).text() + ', '; }); return selected.substr(0, selected.length -2); } }, }); }); 

 .multiselect-selected-text{ display: inline-block; max-width: 100%; word-break: break-all; white-space: normal; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-multiselect/0.9.13/js/bootstrap-multiselect.min.js"></script> <!-- Build your select: --> <select id="example-getting-started" multiple="multiple"> <option value="cheese">Cheese</option> <option value="tomatoes">Tomatoes</option> <option value="mozarella">Mozzarella</option> <option value="mushrooms">Mushrooms</option> <option value="pepperoni">Pepperoni</option> <option value="onions">Onions</option> <option value="cheese">Cheese</option> <option value="tomatoes">Tomatoes</option> <option value="mozarella">Mozzarella</option> <option value="mushrooms">Mushrooms</option> <option value="pepperoni">Pepperoni</option> <option value="onions">Onions</option> <option value="cheese">Cheese</option> <option value="tomatoes">Tomatoes</option> <option value="mozarella">Mozzarella</option> <option value="mushrooms">Mushrooms</option> <option value="pepperoni">Pepperoni</option> <option value="onions">Onions</option> </select>

You could achieve this with the following CSS settings:

.multiselect {
    white-space: normal !important;
    max-width: 200px;
}

white-space:normal lets the text inside the button wrap again and with max-width you can set the maximum width the button should grow to.

See this JSFiddle .

IMHO it is not possible to break the lines using buttonText , eg by inserting <br/> . You can see from the source code of bootstrap-multiselect that in updateButtonText the result of buttonText is inserted using jQuery's html() method and so a <br/> is converted to <br/> .
