Hi Team, we are using your sample code and trying to implement multi-select in the HTML page. but is not able to display properly in all browsers and it always throws the exception as material_select is not a function. Code Used:

// Material Select Initialization
$(document).ready(function() {
    $('.mdb-select').material_select();
});

Html:
<select class="mdb-select md-form colorful-select dropdown-primary" multiple searchable="Search here..">
<option value="" disabled selected>Choose your country</option>
<option value="1">USA</option>
<option value="2">Germany</option>
<option value="3">France</option>
<option value="4">Poland</option>
<option value="5">Japan</option>
</select>
<label>Label example</label>
<button class="btn-save btn btn-primary btn-sm">Save</button>
