<hr color="blue">
最简单的选项卡：
<sx:tabbedpanel id="tab1" beforeSelectTabNotifyTopics="/beforeSelect">
<sx:div label="Tab 1" >
Local Tab 1
</sx:div>
<sx:div label="Tab 2" >
Local Tab 2
</sx:div>
</sx:tabbedpanel>
<hr color="blue">
加载其他页面的选项卡：
<sx:tabbedpanel id="tab2">
<sx:div label="Remote Tab 1" href="upload.jsp">
Remote Tab 1
</sx:div>
<sx:div label="Remote Tab 2" href="multipleUpload.jsp" >
Remote Tab 1
</sx:div>
</sx:tabbedpanel>
<hr color="blue">
设置选项卡底下的内容懒加载，即等需要的时候再加载，使用属性preload="false"：
<sx:tabbedpanel id="tab3">
<sx:div label="Remote Tab 1" href="upload.jsp">
Remote Tab 1
</sx:div>
<sx:div label="Remote Tab 2" href="multipleUpload.jsp" preload="false">
Remote Tab 1
</sx:div>
</sx:tabbedpanel>
<hr color="blue">
固定大小的选项卡,使用属性cssStyle和doLayout：
<sx:tabbedpanel cssStyle="width: 200px; height: 100px;" doLayout="true" id="tab4">
<sx:div label="Tab 1" >
Local Tab 1
</sx:div>
<sx:div label="Tab 2" >
Local Tab 2
</sx:div>
</sx:tabbedpanel>
<hr color="blue">
每次点击选项卡时都重新刷新内容，使用属性refreshOnShow：
<sx:tabbedpanel id="tab5">
<sx:div label="Remote Tab 1" href="upload.jsp" refreshOnShow="true">
Remote Tab 1
</sx:div>
<sx:div label="Remote Tab 2" href="multipleUpload.jsp" refreshOnShow="true">
Remote Tab 2
</sx:div>
</sx:tabbedpanel>
<hr color="blue">
使得其中一个选项卡失效：
<sx:tabbedpanel id="tab6">
<sx:div label="Tab 1" >
Local Tab 1
</sx:div>
<sx:div label="Tab 2" disabled="true">
Local Tab 2
</sx:div>
</sx:tabbedpanel>
<hr color="blue">
设置选项卡在底部显示 (可以是: top, right, bottom, left)：
<sx:tabbedpanel id="tab7" labelposition="bottom" cssStyle="width:200px;height:100px;" doLayout="true">
<sx:div label="Tab 1" >
Local Tab 1
</sx:div>
<sx:div label="Tab 2" >
Local Tab 2
</sx:div>
</sx:tabbedpanel>
<hr color="blue">
设置选项卡允许关闭，使用属性closeable：
<sx:tabbedpanel id="tab8">
<sx:div label="Tab 1" >
Local Tab 1
</sx:div>
<sx:div label="Tab 2" closable="true">
Local Tab 2
</sx:div>
</sx:tabbedpanel>
