K2 SmartForms are customizable forms used in K2 applications to create New items, or Display and Edit existing items in the SharePoint List/Library. Default SharePoint list forms can be replaced with K2 SmartForms which can be easily customized to suit the requirements. Please refer my previous blog for creating SmartForms.
I have a custom list named “K2 Workflow Tutorials” in which I have added the following content types: Item & Custom Content Type. Each Content Type can be set to make use of standard SharePoint forms or K2 SmartForms. In this blog you will see how to manage SharePoint Forms based on Content Type in the K2 Application.
Navigate to the custom list. Click on List tab and then click on Application button under K2 section in the ribbon interface. Click on Form Settings.
Select the Content Type and specify the forms to be used to create, edit or display an item.
