Can't active menu

[Jasonzhangjs]

When the page reloads, the label(li class="active") has been cleared

try to take a look your backend code i think you have a error or your have 2 or more li active declarations. I use the route page for taking the item correct. like this in Symfony 4

<li {{ (app.request.get('_route')[:10]=='dashboard_' ) ? 'class="active"' : '' }}>
          <a href="javascript:void(0);" class="menu-toggle">
              <i class="material-icons">dashboard</i>
              <span>Dashboards</span>
          </a>
          <ul class="ml-menu">
              <li {{ (app.request.get('_route')=='dashboard_sales' ) ? 'class="active"' : '' }}>
                  <a href="{{ path('dashboard_sales') }}">Ventas</a>
              </li>
              <li {{ (app.request.get('_route')=='dashboard_purchases' ) ? 'class="active"' : '' }}>
                  <a href="{{ path('dashboard_purchases') }}">Compras</a>
              </li> 
          </ul>
      </li>
