Boostrap手风琴的宽度过渡

Question

我正在这里进行引导，根据onClick宽度和高度必须增加。我知道了，但问题是宽度随着高度的增加而消失，而高度随过渡而变化。我已经尝试过但无法实现。我的问题是宽度也随过渡而来，第二个问题是当我在几秒钟后单击选项卡时，为什么延迟选项卡才起作用。谁能帮我解决这个问题。

$(document).ready(function() {

  $('.hitw-tabs .collapse').on('shown.bs.collapse', function() {
    console.log('test....');
    $(this).parent().addClass('hitw-tnw');
  });

  $('.hitw-tabs .collapse').on('hidden.bs.collapse', function() {
    console.log('test hidden....');
    $(this).parent().removeClass('hitw-tnw');
  });
});
