我使用div制作了一个下拉菜单(垂直),但我无法获取下拉内容以按下其他菜单(它已经溢出)。
我注意到,当我将代码放入JSFiddle时,它根本没有显示下拉列表,所以我希望这张图片有所帮助。
/*jQuery time*/
$(document).ready(function() {
$("#sidebar_menu .dropbtn").click(function() {
//slide up all the link lists
$("#sidebar_menu .dropdown-content").slideUp();
//slide down the link list below the h3 clicked - only if its closed
if (!$(this).next().is(":visible")) {
$(this).next().slideDown();
}
})
})

#menu_container {
display: block;
position: fixed;
width: 250px;
background-image: url("D:/Website/Website/MyBB_Website/Test/images/black_filter.jpg");
background-repeat: repeat;
height: 100%;
}
#sidebar_menu {
margin-top: 15px;
}
/* The container <div> - needed to position the dropdown content */
#sidebar_menu .dropdown {
position: relative;
display: inline-block;
}
/* Style The Dropdown Button */
#sidebar_menu .dropbtn {
background-color: #2383AF;
color: white;
padding: 12px;
font-size: 15px;
border: none;
cursor: pointer;
width: 250px;
}
/* Dropdown Content (Hidden by Default) */
#sidebar_menu .dropdown-content {
display: none;
position: absolute;
background-color: #185E7C;
min-width: 250px;
box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
}
/* Links inside the dropdown */
#sidebar_menu .dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
/* Change color of dropdown links on hover */
#sidebar_menu .dropdown-content a:hover {
background-color: #F1F1F1;
}
/* Show the dropdown menu on hover */
#sidebar_menuv .dropdown:hover .dropdown-content {
display: block;
}
/* Change the background color of the dropdown button when the dropdown content is shown */
#sidebar_menu .dropdown:hover .dropbtn {
background-color: #2383AF;
}

答案 0 :(得分:3)
#sidebar_menu .dropdown-content
应该有位置:静态而不是绝对。
