Chiming in my support for this feature too! We have a use-case where we need the lead to be able to select whether they would like to provide a home address or practice address and then have the appropriate fields appear. NOTE - in this scenario, we store practice information in the contact record and not the company record.

I need to add a customer assessment/ needs analysis form. Would like one question at a time, and if they answer one way the questions would stop with a message saying they are not qualified.
Commenting to follow this. Would really like to see this feature added.
Fantastic to hear it is in review!!
This would be a very handy solution esp. for handling any regional responsibility,
it will allow us to customize subregions (provinces/states/territories) to match local structures.
Not to mention market segments and -verticals…
Hey guys, just thought I’d add an extra idea ontop of this.
It would be good to also be able to create a dependent field based on the answers of 2 or more fields.
If field A is X and field B is Y, show field C
I really want this, so any process on this?
yes please! this is super necessary, we don’t want to pay typeform or other companies with logic-forms, we prefer to keep it all in one place in our HS account. Thank you!
Any update? My entire company would benefit from this feature. It would make our customer onboarding form possible.
We totally agree with KAnda and all others! We would have an immense benefit from this feature and would be happy to have any update on this!
Hi HubSpot community team 
This would be a major improvement to forms, I’d like to have multiple levels too since they would allow me to better filter and categorize incoming leads with only one form instead of many.
I would also like to volunteer in case the HubSpot Product Team needs testers.
Wishing you all a great week,
Emilia.
Incredible that the request exists for years now, but aside from merging of the same request and “being reviewed” status, not much has been done. Any progress on this idea?
A great idea - we could use this too!
Our example is that Field A containing “123” prompts the dependant Field B to appear. If Field B contains “456”, another Field C is prompted to appear to allow the user to specify more details.
Really need this - we got Hubspot because we were excited about the forms but we may have to go back to using Google Forms for this basic feature.
4yrs of this feature request … ?
likewise, would be really useful.
YESSSS please!
Any update on this Hubspot? Last update from the product team was almost a year ago!
I realize it might not be a “simple” solution, but I will reitterate the challenges we have with country and state/providence pick lists for being a global company. There is no way to maintain hundreds of complicated dependency rules [if Canada, show these providences, if U.S. show these states, etc.] per form AND the workflows to then put the correct data in the native fields so the data integrates with other systems like Salesforce.
A state/country combo is basic, and has been available on simple form systems for 15+ years. 
There are also tons of comments on this thread about various other uses that need these dependencies. Let’s make it a priority!
Hi team,
Commenting for a customer here.
Wondering if we have any updates on this? How I envision dependent fields to work would be similar to workflow (if/then) branch.
I can think of many possible situations where dependent form fields will be super useful as compared to > writing the condition within the form question itself OR setting up multiple forms as a workaround.
Would love an update, thanks (:
This is a feature we really need! Right now we are using smart rules on landing pages to ask multiple layers of questions and it is an incredibly frustrating work around.
Currrently struggling to set up Gravity Forms and Zapier to feed data into Hubspot, since I need more dependencies than HS forms support. Really missing the ability to have multiple dependent fields. The need for this is driven by the criteria used by our sales management to allocate leads.
