我一直在尝试创建一个由下拉列表中的复选框组成的 HTML 表单。我已经能够完成这部分。但是当你点击一个特定的下拉菜单时，剩下的下拉菜单会向下移动。在第二次单击时，下拉列表会折叠并返回到原来的位置。请帮我纠正这个问题。如果复选框可见，我试图保持下拉列表的位置不变。
我想要实现的是类似于http://www.luxuryretreats.com/左侧的过滤器。将不胜感激任何建议！
这是代码。

<script type="text/javascript">
function ExposeList1() {
var showstatus = document.getElementById('ScrollCountry').style.display;
if (showstatus == 'none') {
document.getElementById('ScrollCountry').style.display = "block";
} else {
document.getElementById('ScrollCountry').style.display = 'none';
}
}
function ExposeList2() {
var showstatus = document.getElementById('Scrollguests').style.display;
if (showstatus == 'none') {
document.getElementById('Scrollguests').style.display = "block";
} else {
document.getElementById('Scrollguests').style.display = 'none';

function ExposeList3() {
var showstatus = document.getElementById('Scrollminprice').style.display;

document.getElementById('Scrollminprice').style.display = 'none';
