javascript - Bootstrap v4.3 Navbar 没有正确动画折叠的非导航栏元素的显示过渡

我创建了一个经过修改的药丸菜单系统，该系统在小屏幕和移动设备上显示折叠结构。我遇到的问题是，当按下“菜单”按钮时，如果它们是导航栏的一部分，我希望药丸元素不会显示过渡效果，而是需要大约半秒的时间才能出现，这是不理想。我假设过渡以相对于导航栏的方式工作，因此需要稍微改变方法以显示手动隐藏元素，就像我在下面的示例中那样:

.xs-collapse {
  display: none;
  
}

body {
    background-color: aqua;
}



@media (min-width: 992px) {
  .xs-toggle {
    display: none;
    visibility: hidden;
  }
  .xs-collapse {
    display: block;
     
  }
}
