Hi guys,

How may I include a subsidiary question (see my picture in attachment please). I mean :

I participate to the event

- yes

- no

and then if yes, an other question must be asked :

I take part

- on site

- off site

Thank you in advance for your help.

Kind regards,

Mina

Hello @MinaMos,

The HubSpot feature for this is called [dependent form fields](https://knowledge.hubspot.com/forms/use-dependent-form-fields).

It looks like you’re on a Starter subscription. Dependent form fields require a Professional subscription, see the info box at the start of this article: [Use dependent form fields (legacy)](https://knowledge.hubspot.com/forms/use-dependent-form-fields)

Without a Professional subscriptoin, this is unfortunately not possible.

Best regards!

Sure, @MinaMos. If at some point you need help with evaluating whether a Professional subscription makes sense and what value it could generate, feel free to reach out. Happy to help.
