嘿，伙计们，我需要你们的帮助。这是手风琴引导4的代码。我想让手风琴部分折叠。这意味着隐藏内容的几行应该显示出来，当我们点击按钮时，整个内容必须显示出来。我们能做到吗？如果男士有解决方案，请告诉我。

嗨，欢迎光临。到目前为止，您为实现目标做了哪些工作？也许它与？这不是兄弟..默认的手风琴应该部分折叠，这意味着段落的几行需要显示，其他部分应该隐藏。此外，隐藏部分仅在单击手风琴按钮时显示，显示手风琴的实际行为。有可能吗？哦……我想你误解了我的描述。按钮是卡头。因此，当点击卡片标题时，文本的隐藏部分将显示出来。对不起，描述不好。我也可以给你下面的链接
.card-body {
  max-height: 100px;
}

$('.card-body').on('click', '.btn', function() {
  $(this).closest('.card-body').css('max-height', 'inherit'); 
});
$('#accordionExample').on('hidden.bs.collapse', function () {
  $(this).find('.card-body').css('max-height', '');  // remove max-height when collapsed
})
