我知道wordpress有下拉功能，但由于某种原因它在当前主题上被打破了，我需要它再次使用它。我当前的代码工作，但当我点击父菜单项时，它打开所有子菜单。我只需要打开点击的元素。
我在jsfiddle上发布了我的代码但由于某些原因在jsfiddle上jquery代码不起作用。 的 jsfiddle

JQuery的：
$(document).ready(function() {
$(".accessories").click(function() { //When trigger is clicked...
//Following events are applied to the subnav itself (moving subnav up and down)
$(this).parent().find(".sub-menu").slideDown('fast').show(); //Drop down the subnav on click
$(this).parent().hover(function() {
}, function(){
$(this).parent().find(".sub-menu").slideUp('slow'); //When the mouse hovers out of the subnav, move it back up
});
//Following events are applied to the trigger (Hover events for the trigger)
}).hover(function() {
$(this).addClass("subhover"); //On hover over, add class "subhover"
}, function(){ //On Hover Out
$(this).removeClass("subhover"); //On hover out, remove class "subhover"
});
});

<强> JS： -
$(document).ready(function() {
$(".menu-item").click(function() { //When trigger is clicked...
//Following events are applied to the subnav itself (moving subnav up and down)
$(this).find(".sub-menu").slideDown('fast').show(); //Drop down the subnav on click
$(this).hover(function() {

改为：
$(".accessories").click(function () { //When trigger is clicked...
//Following events are applied to the subnav itself (moving subnav up and down)
$(this).find(".sub-menu").slideDown('fast').show(); //Drop down the subnav on click
$(this).hover(function () {}, function () {
$(this).find(".sub-menu").slideUp('slow'); //When the mouse hovers out of the subnav, move it back up
});
//Following events are applied to the trigger (Hover events for the trigger)
}).hover(function () {
$(this).addClass("subhover"); //On hover over, add class "subhover"
}, function () { //On Hover Out
$(this).removeClass("subhover"); //On hover out, remove class "subhover"
});
你需要当前元素作为选择器而不是它的父元素。
旁注：你的jsfiddle演示不起作用，因为你没有选择任何框架
