Vue.js Accordion should not close if another accordion item is clicked

Time:10-26

I want to make an Accordion menu in vuejs. The Accordion should not close if another div is clicked. It should close when the Accordion item itself is clicked. How do I achieve this?

vue code

new Vue({
el: '#demo',
data () {
return {
  isOpen: false,
  selected: '',
  headerDesktopMenu: {
    menu: {
      menu_items: [{item_name:11111, childrens: [{item_name: 11}, {item_name: 12}]},{item_name:22222, childrens: [{item_name: 21}, {item_name: 22}]},{item_name:33333, childrens: [{item_name: 31}, {item_name: 32}]},{item_name:44444, childrens: [{item_name: 41}, {item_name: 42}]}]
    }
  }
}
},
methods: {
toggleAccordion (item) {
  item == this.selected ? this.isOpen = !this.isOpen : this.isOpen = true
  this.selected = item
}
},
computed: {
accordionClasses () {
  return {
    'is-closed': !this.isOpen,
    'is-primary': this.isOpen,
    'is-dark': !this.isOpen
  };
}
}
})

Vue.config.productionTip = false
Vue.config.devtools = false

HTML code

<div id="demo">
<ul  v-if="headerDesktopMenu.menu.menu_items">
  <li  v-for="(menu, index) in headerDesktopMenu.menu.menu_items" :key="index" : v-if="headerDesktopMenu.menu.menu_items">
      <a  @click="toggleAccordion(menu.item_name)">{{ menu.item_name }}</a>
      <ul  v-if="menu.childrens">
          <li  v-for="(submenuone, indexone) in menu.childrens" :key="indexone" v-if="isOpen && menu.item_name === selected">
              <a >{{ submenuone.item_name }}</a>
          </li>
      </ul>
  </li>

CodePudding user response:

I think you need to keep a list of which top level menu items to display or not display. Something like this.

<template>
  <div id="app">
    <ul  v-if="headerDesktopMenu.menu.menu_items">
      <li
        
        v-for="(menu, index) in headerDesktopMenu.menu.menu_items"
        :key="index"
        :
      >
        <a  @click="toggleAccordion(menu.item_name)">{{
          menu.item_name
        }}</a>
        <ul
          
          v-if="menu.childrens && displayArray[menu.item_name]"
        >
          <li
            
            v-for="(submenuone, indexone) in menu.childrens"
            :key="indexone"

            <a >{{ submenuone.item_name }}</a>
