微信小程序中定义好的几种picker选择器，不管是日期选择器还是地区选择器，或是其他的都有定死的样式和内容。
例如：
但是大多数开发程序的情况下还是需要自己写样式的，或是内容的。
例如：
wxml
<view class="free-dialog {{ showDialog ? 'free-dialog--show' : '' }}">
<ra<a href="/tag/dio/" target="_blank" class="keywords">dio</a>-group class='free-ra<a href="/tag/dio/" target="_blank" class="keywords">dio</a>s' bindchange="ra<a href="/tag/dio/" target="_blank" class="keywords">dio</a>Change">
<label class="free-ra<a href="/tag/dio/" target="_blank" class="keywords">dio</a>" bindtap="click" wx:for="{{items}}" wx:key="{{items}}" data-id="{{index}}" style="{{index==id?'background:#48c23d;color:#fff;':'background:#fff;color:#000;'}}">
<ra<a href="/tag/dio/" target="_blank" class="keywords">dio</a> value="{{item.name}}" name="{{item.value}}"></radio>
<label class="free-text">{{item.value}}</label>
</label>
</radio-group>
</form>css
label{
width:22.5%;
display: inline-block;
border:1px solid #ddd;
padding:10px 0px;
margin:0px 2px 2px;
}
radio-group label radio{
width:100%;
z-index: 3;
display: none;
}
.checked{
background:#48c23d;
color:#fff;
}
radio-group label .free-text{
width:100%;
text-align: center;
display: inline-block;
}
