下拉列表加style

<div style="z-index:9999;position:relative;">
<select class="speedSelect" name="str">
<option>请选择</option>

<c:forEach items="${list1 }" var="k1">
<option value="${k1.typeId},${k1.typeName}" <c:if test="${knowledge.typeId==k1.typeId }">selected</c:if> >

${k1.typeName }

</option>

</c:forEach>
</select>
</div>
