How can I make form fields mandatory?

How can I make the field like Address, Phone Number mandatory?

Hi silknsew1,

Here's how you can make a particular field mandatory:

1. Select the element in the Form Builder.
2. Click the Settings (gear) icon.
3. Under the General tab, toggle Required to “On” to make the field mandatory.

Let us know if there’s anything else we can help you with. 

I am asking in app builder

Hello silknsew1,

Thanks for reaching out to Jotform Support. Unfortunately, it is not possible to require a field, as Jotform App is not intended to collect information. However, you can consider creating a form and required the necessary field in the form, then embedded it in your Jotform App.

Let us know if you have further questions.
