Embed doctype in another doctype

hi all , is there any way to embed embed doctype in another doctype appear when you try to add new row/doc !

You need to be MUCH more specific.

Show, with pictures &/or properly formatted code samples, what you have tried so far, what worked, what failed.

As it is now, it is very difficult to understand what you are trying to do.

I have the fees doctype in the education module , I need a way to embed this list of fees or the hole fees doctype to be asperse when I create new payment entry .

Have you looked at Customize ERPNext / DocType.

About 15 minutes into the video at the bottom of the page, a new DocType “Picking List” is created. At 16:35 it shows how to add a child table.

Does that serve your needs?
