<ol class="breadcrumb float-sm-right mr-4" >
<li class="breadcrumb-item"><a href="<?php echo e(admin_url('/'), false); ?>"><i class="fa fa-dashboard"></i> <?php echo e(__('Home'), false); ?></a></li>
<?php for($i = 2; $i <= count(Request::segments()); $i++): ?>
<li class="breadcrumb-item">
<?php echo e(ucfirst(Request::segment($i)), false); ?>
</li>
<?php endfor; ?>
</ol>
<?php endif; ?>
