Enable tab only when required fields are completed

How can I enable a tab ONLY when required fields are completed?

Can you please give us more details about what you are trying to achieve?

Required fields can't be skipped so it will always ask a value but if you mean to say enable or show a group of fields when a certain field is filled, then here's how to do that with conditions http://www.jotform.com/help/196-How-to-Hide-or-Show-Multiple-Fields-at-Once-Based-On-a-Single-Conditional-Entry

If you require further assistance, let us know.

I have several required fields on my Nursing CAP DOcumentation submission form. On my form there are also multiple tabs. Example if on Part A Requirements tab the user does not complete required fields but he goes directly to Submit Requirements tab. I want the user to not go directly to Submit Requirements tab unless they complete Part A and Part B Required fields.

Is this possible?

Unfortunately, it is not possible to hide particular tab of the form as they are not form elements. Tabs are the layout option performed by Form Tabs widget. 

But, I can suggest hiding fields under that tab by adding a conditional statement. For example:

Here is my test form: https://form.jotform.com/81043990184963

There is another way as well, to use Section Collapse element instead of Form Tabs. It would allow to hide the section, which includes Submit Part A and B fields:

Hope this helps. But, please let us know if you need further assistance.

Thank you.

Ok those options will not work for us. How about the bottom of the screen where you have Next or Back? Can we disable those based on conditionality? If required fields are not completed next will not be available on that tab?

The form tabs widget actually has an option that would prevent users from moving to the next page by clicking the tabs without filling the required fields on the current page.

Here's how:

About your workaround, yes, it is possible to hide page breaks (next and back buttons) through show/hide condition.

Thank you. This answers my questions.
