I am trying to add some additional fields into the issue module. And I am opening the module in the portal for my users. There is no problem for me to add the additional fields to the the issue form. However, I can see the web form for issues is classified as standard form and I am not able to modify it (it is read only) to show more field on the portal for the users.
What will be a best way to show the additional fields in web form?
