Hi Ravi,
I am not sure what you are asking here regarding how to set priority levels from 1 to 3 in list_cr.htmpl. That for is a list form which is used for searching request tickets and showing the results in a list. I am not sure what you mean by "set priority levels" in that form. Can you clarify?
The replies from both Paul and Kyle are correct here. We do not support the removal of priority values, however, the documents provided by Kyle do tell you how to hide them so that end users and/or analysts cannot see the ones that you want to block.
Please review the documents provided and let us know if you have further questions.
Thanks,
Jon I.
