Many Bloggers were asking how to create a rolling label or tag cloud, so I wanna share how to create it.

This the following steps :

2. Select layout tab
3. Select Edit HTML
4. Check Expand Widget Templates
5. Copy-paste code after this code
<b:section class='sidebar' id='sidebar' preferred='yes'>

<b:widget id='Label129' locked='false' title='Labels' type='Label'>
<b:includable id='main'>
<b:if cond='data:title'>
<h2><data:title/></h2>
</b:if>
<div class='widget-content'>
<script src='http://elmubarok.fileave.com/labelclouds.js' type='text/javascript'/>

so.addParam("allowScriptAccess", "always");
so.write("flashcontent");
</script>
<b:include name='quickedit'/>
