the button doesn’t send any function in web hosting, in localhost everything work perfectly and also it only happen to multiple devices and the rest device can access app perfectly too without any issue. it make me confused what I miss.

`<ul class="navbar-nav bg-gradient-primary sidebar sidebar-dark accordion" id="accordionSidebar">
    <form id="admindb-form" action="<?php echo site_url('absensi/admin'); ?>" method="post" style="display: inline;">
             <li class="nav-item">
                  <a class="nav-link" onclick="document.getElementById('admindb-form').submit();">
                  <i class="fas fa-fw fa-chart-area"></i>
                 <span>Dashboard</span></a>
             </li>
      </form>
        <li class="nav-item">
                <a class="nav-link collapsed" data-toggle="collapse" data-target="#menuinfo"
                    aria-expanded="true" aria-controls="collapsePages">
                    <i class="fas fa-fw fa-folder"></i>
                    <span>Info Data</span>
                </a>
                <div id="menuinfo" class="collapse" aria-labelledby="headingPages" data-parent="#accordionSidebar">
                    <div class="bg-white py-2 collapse-inner rounded">
                        <h6 class="collapse-header">Data Informasi:</h6>
                        <form id="datainfo-form" action="<?php echo site_url('informasi/infos'); ?>" method="post" style="display: inline;">
                            <input type="hidden">
                            <a class="collapse-item" onclick="document.getElementById('datainfo-form').submit();">Data Informasi</a>
                        </form>
                    </div>
                </div>
           </li>
</ul>`

admindb-form working
this menu info doesn’t show the collapse item
it’s like data-parent = #accordionSidebar doesn’t readed

already clear cache, use other web browser and several device but it same
