Hi Guys

I am facing a complicated issue of partially locking content on textarea type fields. So far I have searched a lot in Google but nothing seems to have happened as I haven't found any help what so ever. Following is what client wants:

I want to have some of pre-populated contents to be uneditable by the user and only they can add there own contents in the html templates.

Is that really possible to do this using javascript/jquery library ?

If someone knows anything about this,please let me know.

Thanks in advance.
