easyui的手风琴accordion的宽度如何设置成百分比

[林小花~]

easyui的accordion的宽度如何设置成百分比，而不是690px,我设置成100%，好像显示的100px(fit:true不能满足我的要求，他会强制覆盖，显示不出我页面所有数据),求大佬解答

<div class="easyui-accordion" id="ac" style="width:690px;" >
<div title="街道" style="padding:10px;" id="acc1" >
<c:if test="${Page.picIndexList == null}">
<tr><td>无现场照片!</td></tr>
</c:if>
<c:if test="${Page.picIndexList != null}">
<c:forEach items="${Page.picIndexList}" var="picvo">
<c:if test="${picvo.kcType == '1'}" >
<tr>
<td><img src="data:image/png;base64,${picvo.thumbnail}"
width="80px"
height="80px" class="pimg"></td>
</tr>
</c:if>
<c:set var="count1" value="0" scope="request"/>
<c:if test="${picvo.kcType != '1'}" >
<c:set var="count1" value="${count1+1 }"/>
<c:if test="${count1<2 }">
<tr>
<td>无现场照片!</td>
</tr>
</c:if>
</c:if>
</c:forEach>
</c:if>
</div>
