Question

我尝试在此菜单中更改子菜单的位置。我将ul标签的位置更改为相对但是它没有正常工作。当点击菜单时，子菜单显示但主菜单由子菜单缩放。请咨询

<div id="cssmenu" style="direction:rtl;">
            <ul><li class="mobile"><a href="#"><span>Menu <i>☰</i></span></a></li>
    <li class="">
            <a href="http://localhost/dnn_test/"><span>صفحه نخست</span> </a>
        </li>
    <li class="has-sub active">
        <a href="http://localhost/dnn_test/skin2"><span>skin2</span> </a>
            <ul style="display: block;">
            <li class="">
            <a href="http://localhost/dnn_test/sub_skin2"><span>sub_skin2</span> </a>
        </li>
    <li class="">
            <a href="http://localhost/dnn_test/sub1_skin2"><span>sub1_skin2</span> </a>

Answer 1

这是我的解决方案/建议：

将子菜单的位置更改为absolute，以便将其从文档流中取出。确保将父li设置为relative：

#cssmenu ul ul {
  ....
  position: absolute;
  text-align: left;
  ....
}
