Need multi-forms

I need a way to use one main form to access multiple other forms.

Ideally, the main form would have a drop-down list where each option selected switched the user to the associated independent pdf fillable form. (similar to a dynamic drop down)

is there a Widget or Integration I am not seeing that would allow this?

It is possible to redirect form submission using Conditions feature. Example, you can redirect the user to another form after they submit the main form base on the selected option or answer they did in the form.
