如何扩展绝对定位列表

Question

是否可以告诉绝对定位的列表项将下一个列表项向下推？ https://jsfiddle.net/230cfs4g/ 在此示例中，子菜单下的列表项与其下的链接重叠。

我的目标是让它下推其他链接，类似于移动版本（包含）的功能，同时仍然保持悬停在您期望从桌面菜单中获得的内容方面..

Answer 1

我认为在这种情况下不应该绝对定位。请参阅此请求。

jQuery('.menu-item').each(function() {
  let _this = jQuery(this);
  if (_this.children('ul').length) {
    _this.addClass('menu-item-with-children');
  }

});
jQuery('.menu').on('click', '.menu-item > a', function(e) {
  e.preventDefault();
  if (!jQuery(this).hasClass("active")) {
    jQuery(this).addClass('active')
    jQuery(this).next('ul').addClass('active')
    jQuery(this).children().addClass('active')
    jQuery(this).parent().addClass('active').siblings().find('.active').removeClass('active')
      .parent().removeClass('active');
  }

  //Not sure why this works but what the hell.
  else if (jQuery(this).removeClass('active')) {
    jQuery(this).next('ul').removeClass('active')

    jQuery(this).children().removeClass('active')
    jQuery(this).parent().removeClass('active').children().find('.active').removeClass('active').siblings().find('.active').removeClass('active')
      .parent().removeClass('active');
  } else {


    jQuery(this).parent().removeClass('active').siblings().find('.active').removeClass('active').children().find('.active').removeClass('active')
      .parent().removeClass('active');
  }


  //Unused atm, may need lader
  //else if (jQuery(this).removeClass('active')){
  //jQuery(this).next('ul').removeClass('active')

  //      jQuery(this).children().removeClass('active')
  //jQuery(this).parent().removeClass('active').siblings().find('.active').removeClass('active')
  //.parent().removeClass('active');
  //     }

Answer 2

.sub-menu * {position: static;} 显然是我所有问题的答案。
