【问题描述】:
我刚刚创建了我的拳头下拉菜单,到目前为止一切都很好。下拉菜单打开。下拉按钮下方是容器中的文本和图像。 当我单击下拉按钮时,列表位于容器中的文本和图像后面。如何将下拉列表置于前台?
<td bgcolor="white" height="50">
<div class="dropdown">
<button onclick="myFunction()" class="dropbtn"><FONT face="Verdana" color=#026991 size=2><b>Onze diensten</b></button>
<div id="myDropdown" class="dropdown-content">
<a href="#"><b>Link 1</b></a>
<a href="#"><b>Link 2</b></a>
<a href="#"><b>Link 3</b></a>
<a href="#"><b>Link 4</b></a>
<a href="#"><b>Link 5</b></a>
</div>
</div>
<script>
/* When the user clicks on the button,
toggle between hiding and showing the dropdown content */
function myFunction() {
document.getElementById("myDropdown").classList.toggle("show");
}
// Close the dropdown menu if the user clicks outside of it
window.onclick = function(event) {
if (!event.target.matches('.dropbtn')) {
var dropdowns = document.getElementsByClassName("dropdown-content");
var i;
for (i = 0; i < dropdowns.length; i++) {
var openDropdown = dropdowns[i];
if (openDropdown.classList.contains('show')) {
openDropdown.classList.contains('show');
}
}
}
}
</script>
CSS:
/* Dropdown Button */
.dropbtn {
background-color: white;
color: #026991;
padding: 16px;
font-size: 16px;
border: none;
cursor: pointer;
}
/* Dropdown button on hover & focus */
.dropbtn:hover, .dropbtn:focus {
background-color: white;
border: none;
}
/* The container <div> - needed to position the dropdown content */
.dropdown {
position: relative;
display: inline-block;
}
/* Dropdown Content (Hidden by Default) */
.dropdown-content {
display: none;
position: absolute;
background-color: white;
min-width: 160px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
}
/* Links inside the dropdown */
.dropdown-content a {
color: #026991;
padding: 12px 16px;
text-decoration: none;
display: block;
}
/* Change color of dropdown links on hover */
.dropdown-content a:hover {background-color: white}
/* Show the dropdown menu (use JS to add this class to the .dropdown-content container when the user clicks on the dropdown button) */
.show {display:block;}
