How to display dropdown options conditionally?

I would like to know how can I insert the conditional below:

Example:

Combobox1:

brand vehicle:

Option1: GMC

Option2: Honda

Option3: Toyota

Combobox2:

model of the vehicle:

If I selection the Option2: Honda

The option in combobox2 should be:

Option1: Accord

Option2: Civic

Option3: FIT

Option4: CR-V

and, if I selection the Option3: Toyota

The option in combobox2 should be:

Option1: Camry

Option2: Corolla

 Could you help me?

Thank you.

Hello leonardonit82,

There are two options available to achieve your requirement:

#1. You can add one new dropdown for every option and then add conditions to show / hide the respective dropdown box based on the selection of first dropdown. Please check the screenshot below on how to do this:

#2. Alternative option is to go ahead and add "Dynamic Dropdowns" widget in your form which will allow display nested dropdown fields.

Please take a look at the following demo form where I have gone ahead and added both the options explained above :  http://form.jotformpro.com/form/51110945718958? 

Feel free to clone the form for a closer look. The following guide should help you in form cloning:  http://www.jotform.com/help/42-How-to-Clone-an-Existing-Form-from-a-URL
