我有以下列出的输入形式,这些输入形式以下列形式使用:
<li data-input-trigger>
<label class="fs-field-label fs-anim-upper" for="q3" data-info="This will help us know what kind of service you need">How happy are you with our service today?</label>
<br>
<!--This will help us know what kind of service you need-->
<div class="fs-radio-group fs-radio-custom clearfix fs-anim-lower">
<span><input id="q3d" name="q3" type="radio" value="ok"/><label for="q3d" class="radio-ok"></label>Very Unhappy</span>
<span><input id="q3e" name="q3" type="radio" value="mobile"/><label for="q3e" class="radio-mobile">Unhappy</label></span>
<span><input id="q3c" name="q3" type="radio" value="bad"/><label for="q3c" class="radio-bad"></label>Nutral</span>
<span><input id="q3a" name="q3" type="radio" value="conversion"/><label for="q3a" class="radio-conversion">Happy</label></span>
<span><input id="q3b" name="q3" type="radio" value="social"/><label for="q3b" class="radio-social"></label>Very Happy</span>
</div>
</li>
有人知道我如何才能使列表的选择成为强制性的,即是必需的,我知道这可以通过标准的html表单输入来完成,但不能使用概述的列表?
