How to use "form_remote_tag" to retrieve the values


Hi all,

I am validating a form, wherein i could display all the error messages
are displayed in the same page, but the problem is whenever it displays
the errors at the same time it is refreshing all the fields.

Instead, I am interested in preserving the validated values but
refreshing only the fileds that failed validations and corresponding
message to be displayed.

In some post i read about form_remote_tag can do this, but can anyone
provide me more details/explanation.

Thanks in Advance,
