BootstrapVue 崩溃并打开和关闭所有按钮

Question

这个问题困扰我一段时间了。

谁能帮我弄清楚如何构建多个单独打开和关闭的 BootstrapVue 折叠。事实上，单独打开和关闭已经可以工作了，因为它是开箱即用的。我希望“打开”和“关闭所有”按钮在任何时候按下时打开所有或关闭所有折叠。

new Vue({
 el: "#app",
 data: {
  showCollapse: false
 }
});

<div id='app'>
   <div class="row">
      <div class="col-12 mt-2">
      
         <h1>Vue with BootstrapVue collapse and open and close all buttons</h1>
         <p class="lead">The purpose of this pen is to build multiple BootstrapVue collapses that open and close individually. However we want the Open and Close all buttons to open all or close or collapses when pressed.</p>

感谢 Discord 上的 BootstrapVue 社区。我们想出了这个 CodePen 来展示正确的功能。

new Vue({

 data: {
  collapses: [ 
     { show: false },
     { show: false },
     { show: false }
  ]
 },
 methods: {
    openAll() {
       this.collapses.forEach(collapse => {
          collapse.show = true
       })
    },
    closeAll() {
       this.collapses.forEach(collapse => {
          collapse.show = false
       })
    }
 }
});
