Is there the possibility of mixing TMS Web core Components and html template form inside TabSheet ?

I would like to create an application body with TMS components and mix with html templates.
Have a top main menu in NavBar and below main container TwebPageControl and for each of the TWebTabSheet link with a TWebForm = Custom Html Form.

Maybe it's easier to create everything in HTML (SPA) ?

Thank you.

PS :
I've try with Application.createForm(TCustomForm,'TWebTabSheet_Name',MyCustomFormVar)
but it's failed because TWebTabSheet_Name must be an HTML element.

I suggest to have a look at the form hosting demo and where the form hosting demo shows sub forms in a panel, do this in the tabsheet here.
