你可以试试这个

$('#select_id').select2({ minimumResultsForSearch: -1 });

它关闭搜索结果框，然后设置控件不可见

你可以在select2文档select2文档中检查

查看这个线程https://github.com/ivaynberg/select2/issues/489，您可以通过将minimumResultsForSearch设置为负值来隐藏搜索框。

$('select').select2({
    minimumResultsForSearch: -1
});

如果你有多个属性在你的选择，这个肮脏的hack工作:

var multipleSelect = $('select[name="list_type"]');
multipleSelect.select2();
multipleSelect.parent().find('.select2-search--inline').remove();
multipleSelect.on('change', function(){
    multipleSelect.parent().find('.select2-search--inline').remove();
});

查看文档https://select2.org/searching#limiting-display-of-the-search-box-to-large-result-sets

如果你想隐藏在初始打开，你正在通过ajax调用填充下拉列表，在你的select2声明的ajax块中添加以下内容:

beforeSend: function () 
  {
    $('.select2-search--dropdown').addClass('hidden');
  }

然后在ajax请求成功后再次显示它(并聚焦):

  success: function() {
      $('.select2-search--dropdown').removeClass('select2-search--hide'); // show search bar then focus
      $('.select2-search__field')[0].focus();
  }

我喜欢根据选择中的选项数量动态地执行此操作;隐藏搜索选择与10或更少的结果，我做:

$fewResults = $("select>option:nth-child(11)").closest("select");
$fewResults.select2();
$('select').not($fewResults).select2({ minimumResultsForSearch : -1 });
