Feature Request: if/then option and radio buttons w/added text field option

First I am not a developer but I have googled and scoured the forums for help but may not know exactly what to search for. Thanks in advance for any direction or advice.

Scenario: Creating a permission slip for a youth group which should be simple but they’ve started to ask for additional features.

• Example 1 – Simple Yes/No Field but if “Yes” trigger an addition (required) field for further information.
  • I’ve provided just a second field for extra info and stated in the Help Text “if Yes please provide detail”. This works but I wondered if it could be tied to the next field with an If/then statement or something like it.
• Example 2 – They want to identify if a phone number is Cell, Home, or Work. I know…seems odd in this day and age but they are trying to follow an old paper form that offered those options.
  • Is there a way to use a single field like radio buttons to select along with a text/numeric field? Similar to the radio buttons/other field.
    • I currently just use two fields, one to identify Phone Type and another to get the phone number with some regex to keep the input consistent.
  • Example 3 – Free form text between Fields for added context or clarity.
    • Tried many settings and found the “Heading” option but I couldn’t ever get the field to show up on my form. I read the forum and saw there were some extra steps to get it in place, but for the life of me, I couldn’t ever get it to be visible on the form.
  • Example 4 – On my form I have different areas where a phone number is requested (e.g. Participant, Guardian 1, Guardian 2, Emergency Contact, etc). However, I don’t want to make every one of these phone fields “required” but I do want input validation if they choose to enter data in these optional fields.
    • I am doing my validation via regex. If I set the field to use regex, it makes it a “required” field. Is there any way around this?
