问如何使下拉菜单工作，而不使下面的内容在点击时向下移动

EN

$(document).ready(function(){
var dropOneValue = "";
		$("ul.which-way").on("click", function() {
		$(this).find('li').toggleClass("open-list");
		$(this).find('open-list').css("display", "block");
		});
		$("li.cadja").on("click", function(){
			console.log($(this).find('.value').html());
      dropOneValue = $(this).find('.value').html();
       $($(this).parent().find('.which-init')[0]).html($(this).html());
		});  

		$('a#trip').on("click", function(){
			$(this).attr("href", "https://www.westcoastway.co.za/"+dropOneValue);
		});
		
		$('a#tour').on("click", function(){
			$(this).attr("href", "http://capeytours.co.za/west-coast-tours/"+dropOneValue);
