Hello,

 

Based on the below link,

 

 

<div contenteditable="false" style="border-right: #ff0000 0px dotted; border-top: #ff0000 0px dotted; border-left: #ff0000 0px dotted; border-bottom: #ff0000 0px dotted; height: 20px" unselectable="ON"><font size="5">This Heading is not editable.</font>...</div>

 

I have found part of the solution to my question.But, now when i modify this as  contenteditable="true", it is not wrking.

Thanks for your help in advance.
