I have a custom content type and list on a SharePoint 2010 server. The edit/add forms are custom, built in SharePoint Designer. I want to modify the layout of the forms including a new field, but the target server does not and will not have SharePoint Designer. In addition, current list data and views already exists on the target server. Is there a way to customize these forms on the target server without destroying the current data and all the views the user already added?
Thanks in advance for your help
