    Adding additional fields to form.

    Hello All,
    I currently have this page Rahman | Khaliq | Contacts
    What I am trying to do is have a guest choose yes or no, if they choose no, and click submit. I will get The answer no with their name to my email.

    If they choose Yes, then I want a dropdown box to appear with numbers 1 though 10. If they choose 1, then a input box shows up so they can put the name of the guest. If they choose 2 then 2 input boxes show up, so on and so forth.

    All fields should be required if they choose yes.
    The submit should send me the results to my email...

    Let me know your guys thoughts.
    Thank you very much.

                document.getElementById("dynselect").style.display = "block";
                // todo: set required for this select
    // todo: hide select and remove required when "no" is clicked
    document.getElementById("dynselect").addEventListener("change", function () {
        // create a list of all inputs
        var inputs = document.querySelectorAll("#dyn2 input");
        // loop through these inputs
        for (var i = 0; i < inputs.length; i++) {
            // provide current input
            var cinput = inputs[i];
            // check if this input has class according
            // value of the selected option
            if (cinput.classList.contains(this.value)) {
                // input should be enabled and visible
                cinput.parentNode.style.display = "block";
                cinput.setAttribute("required", true);
            } else {
                // input should be disabled and invisible
                cinput.parentNode.style.display = "none";
                cinput.setAttribute("disabled", true);
    so now I still dont see the submit btn that enters results to email as well as clicking no showing nothing just the submit btn. Dynamic form
