如何一次打開所有 Bootstrap 手風琴標簽

Question

我有以下手風琴，並希望允許用戶使用 jQuery 單擊按鈕來展開所有手風琴選項卡。

我已經嘗試過使用這種方法（ https://codepen.io/dikuw/pen/KgzvJp ），但手風琴位於 Kendo 自定義編輯模板彈出窗口中，而不是展開所有面板，它只是切換第一個面板的打開和第二個面板。

---- JavaScript的---代碼

$('.closeall').click(function () {
        $('.panel-collapse.in')
          .collapse('hide');
    });
    $('.openall').click(function () {
        $('.panel-collapse:not(".in")')
          .collapse('show');
    });

這在您給的Codepen中對我有用。

Answer 3

這在引導程序 5 中對我有用

$(".closeall").click(function () {
    $(".collapse").removeClass("show");
});
$(".openall").click(function () {
    $(".collapse").addClass("show");
});
