How to add a custom symfony form?

Custom Symfony Form & Twig Templates

My goal is to create a pure symfony form in sulu. I am a using the default sulu admin ui and have not extended anything.
I have a contact page (a twig html page) where I want to render my custom symfony form into.

I am not using any custom controllers or entites etc.

How do I do that?

@nlipkanov for "pure symfony" form you don't need a SuluFormBundle you Create a Custom Controller for your Sulu Template and handle the Form there like you would do it in a normal Symfony Application.

The Sulu Form Bundle allows the Content Manager to create Forms, this specially make sense for simple forms like a "Contact" Form. Any form without a special business Logic behind it. So the Content Manager can decide which fields he want and should be shown for that form.

Okay, but how do I access e.g. like $attributes['myData'] = 'data from frontend controller!'; in my twig template?

It is available under myData if you don't know your available variables do {{ dump() }} in twig.

Thanks! I see my variable now.
Is this anywhere documented? Because I could not find it in the docs.
