如何從Select2的optgroup中選擇子選項？

問題： 我已經成功創建了一個帶有組的 select2 模板，但我無法選擇其中的專案，我在下面制作的代碼中是否缺少任何內容？你的任何幫助對我來說意義重大，謝謝

代碼 ：

$("#payment").select2({
  placeholder: 'Payment',
  width: 'resolve',
  minimumResultsForSearch: Infinity,
  templateResult: function formatState(state) {
    if (!state.id) return state.text;
    var $state = $(
      '<span><img src="'   state.icon   '" style="width:30px;"/> '   state.text   '</span>'
    );
    return $state;
  },
  ajax: {
    url: base_url   'user/api/payment',
    dataType: 'json',
    processResults: function(data) {
      return {
        results: $.map(data.data, function(item, key) {
          var children = [];
          for (var k in item.children) {
            var childItem = [];
            childItem.id = item.children[k].id;
            childItem.icon = item.children[k].icon;
            childItem.text = item.children[k].text;
            children.push(childItem);
          }
          return {
            text: item.text,
            children: children,
          }
        })
      };
    },
  }
});

據我在您的代碼中所見，您的 API 正在回傳已格式化的結果，因此請保持簡單。請使用基于您的代碼的完整作業示例檢查此小提琴。

$("#payment").select2({
placeholder: 'Payment',
width: 'resolve',
ajax: {
    url: 'https://randomuser.me/api/', //a random URL to simulate a request response in jsfiddle
    dataType: 'json',
    processResults: (data) => ({ results: response.data })
}
});
