带滚动条的Jqgrid多选下拉列表

我想在我的应用程序中添加带有复选框的多选下拉列表，我已经添加了它，它工作得非常完美。多重选择已启用，但其高度未设置，这是我的视图。。。请帮忙

看法

对于我在之前的评论中多次向您提出的问题，您仍然没有回答：您使用的是哪个版本的jqGrid，来自哪个分支的jqGrid（、商业版或jqgridI v5.0.2版本中的旧jqGrid Development alternative fork无法帮助您进行商业版。您可以将问题发布在上，或等待其他开发人员可能会帮助您。您应该以任何方式编辑问题的文本，并添加jqGrid产品的名称、版本号和multiselect p的名称lugin和问题的版本号。您应该填写您使用的编辑模式（表单编辑、内联编辑或单元格编辑）。
