                        <span class="caret"></span>
                        <span class="sr-only">Toggle Dropdown</span>
                    </button>
                    <ul class="dropdown-menu" role="menu">
                        <li><a href="#">Delete</a></li>
                    </ul>

            </div><!-- /input-group -->

<div class="mails">
            <table class="table table-hover table-condensed">
                <?php
                if(count($inMessages)>0)
                    foreach($inMessages as $m):
                        ?>
                        <tr data-id="<?php echo $m->sn?>" <?php if($m->flag==1) echo "class=\"read\""?><?php if($m->flag==0) echo "class=\"unread\""?>>
                            <td><?php if($pagetitle!="Trash"):?><i class="fa fa-check-square-o fa-square-o disabled" data-id="<?php echo $m->sn?>"></i><?php endif?></td>
