<div class="col-sm-3 col-md-2 sidebar">
        <ul class="nav nav-sidebar">
            <li style="margin-left:20px;">

            </li>
            <li><a href="#"> @ {{ Auth::user()->name }}</a></li>
            <li class="active"><a href="#">PREGO<span class="sr-only">(current)</span></a></li>
            <li><a href="#">Edit Account</a></li>
