我正在使用http://isteven.github.io/angular-multi-select/中的angular-multi-select 。它根据我的需要工作。我使用模态形式的多重选择，我想验证它，但是当我使用必需的选项时它并没有验证。谁能建议我如何验证形式的角度多重选择。

提前致谢
我只是使用了具有相同输出模型的不可见输入字段。并将其设置为显示：无。
<div class="col-md-11">
{{batch_form.start_time.$error.required}}
<div multi-select
input-model="batch_timing.days"
output-model="resultData"
button-label="acronym"
item-label="acronym symbol name"
tick-property="ticked"
helper-elements="all none reset">
</div>
<input type="text" ng-model="resultData" name="days" style="display:none" required />
但是请谨慎使用名称-只需从多选中删除名称属性，然后将其添加到隐藏的输入字段即可。
