My question came from this Display field ONLY in edit mode using Page Layout
To Achieve this functionality.
First goto any Account detail page. Select name field and press F+12 to open console. Now there you can see the Name field inside td. So I copied the id.
We can't use the VF page. Reason salesforce doesn't allow us to perform cross site scripting.
Not sure this is possible or not. Need Experts feedback.
Thanks in Advance
