How To Control Blogger’s Official Widgets?

The same procedure can be applied to Blogger’s official widgets like About Me, Archives, Poll etc. For controlling that widgets do this,

1. Go To Blogger > Design > Edit HTML
2. Backup your template
3. Check the Expand Widgets Templates Box
4. Search for the title of the widget you want to control
5. The code for the widget will look something similar to this one,

<b:widget id='HTML' locked='false' title='WIDGET-TITLE-HERE' type='Profile'>
<b:includable id='main'>
LARGE CHUNK OF WIDGET CODE 
</b:includable> </b:widget>

On finding the title in place of WIDGET-TITLE-HERE you will find two similar codes like those I have shown in bolded blue  You just need to add the Controlling codes in the following manner. For example if you wish to show a widget at Homepage only then do this,

<b:widget id='HTML' locked='false' title='WIDGET-TITLE-HERE' type='Profile'>
<b:includable id='main'>
<b:if cond='data:blog.url == data:blog.homepageUrl'>
LARGE CHUNK OF WIDGET CODE 
</b:if>
</b:includable> </b:widget>

That’s it. Do the same for applying any controlling code. I hope this was useful :)
