Polymorphisme pour create.cshtml/create.cshtml.cs ?

Hi,
I have a model class named "Paragraph Line"
and two other classes, Paragraph and Summary, which both contain a collection of Paragraph Lines. Paragraph line has foreign keys Guid? ParagraphId and Guid? SummaryId, filled in according to the attachment to a paragraph or a summary.
I have a "create" form for a Paragraph Line, but the behaviors are different depending on the type of the parent (notably the GetParent(parentId) method which returns an instance of Paragraph or of Summary).
I am thinking of using polymorphism for the Create.cshtml and Create.csthml.cs files, can you give me advice on the best way to manage?
Thanks in advance.

Not sure what kind of effect you want to achieve? How about add a DropDownList in the Create page, and use it to let user select whether is a Paragraph or a Summary?

It's because you create the Paragraph Line from Paragraph or from Summary. The user can't modify nor select parent type.
You can see the using in the picture.

From the picture, the new Paragraph Line is added under the specified Paragraph or from Summary, in my opinion, when I click the button, I will use JQuery to get its parent element's (Paragraph and Summary) primary key, use JQuery Ajax transfer the new Paragraph Line and the primary key to the backend, and then insert the related data into database. You can try to use this method.
