如何为 select2 列表的每个项目创建一个按钮？

Question

我需要在加载期间在 select2 组件中的每个列表项旁边创建一个按钮（视图）。我在网上找不到任何可以帮助我的东西。有人知道怎么做吗？

$("#MySelect2").select2({
    tags: "true",
    createTag: function () {
        // Dessabilita a inserção quando Enter for pressionada
        return null;
    },
    placeholder: "Selecione uma opção",
    allowClear: false,
    width: '100%',
    dropdownParent: genericModal,
    language: {
        noResults: function () {
            return "Nenhum resultado encontrado";
        }
    }
});

<div class="col-md-4">
    <label asp-for="ParentescoTipoId" class="control-label">Tipo de Parentesco</label>
    <select asp-for="ParentescoTipoId" asp-items="Model.ParentescosTipos" id = "MySelect2" title="Selecione uma opção" class="form-control sel-pessoa-fisica-parentesco-parentesco-tipo" style="position: fixed !important;"><option value=""></option></select>
    <span asp-validation-for="ParentescoTipoId" class="text-danger"></span>
</div>

谢谢:)

这应该可以做到。
你必须使用 templateResult.
这样就可以为每个元素添加一个按钮。
为了唯一性，我添加了一个 data-id 属性。

$(document).ready(function() {
  $('.js-example-basic-single').select2({
    minimumInputLength: -1,
    placeholder: 'Search',
    data: [{
      id: 1,
      text: "First"
    }, {
      id: 2,
      text: "Second"
    }],
    templateResult: function(data) {
      var $result = $("<span></span>");
      console.log('data', data.id);
      $result.text(data.text);
      $result.append('<button data-id="' + data.id + '" class="btn">' + data.text + '</button>');
      return $result;
    }
  });
});

.btn {
  float:right;
}

.js-example-basic-single {
  width: 100%;
}
