The Attach File section in the portal Entity Form has two important attributes - Attach File Save Option and Accept File Types. As I understand, the Attach File Save Option is key to attaching files in CRM Notes and Accept File Types is used for specifying acceptable file types.
These two attributes are missing in the Web Form Step form which means we cannot specify where to store the attached files (note there is another attribute Attach File Storage Location but it doesn't seem to work) and restrict attachments to given file types.
Can someone please suggest the best way of handling attachments through web form steps? I know it can be done through notes but from a portal user perspective, it is not a great experience.
