How to collapse/expand accordion in a Q&A form after input selection

Not sure if that’s the correct vocabulary, but here’s what I’m trying accomplish. I’m working with a team on this big multi-page Q&A application, my task is make one particular page use the least amount of screen real estate as possible.

I’m using an accordion, each one has a question inside, and next to each question is a question mark which changes to check mark after the question is answered.

I have all that already completed which you can see here:

$(document).ready(function() {

  $(".accordion_head").click(function() {
    if ($('.accordion_body').is(':visible')) {
      $(".accordion_body").slideUp(300);
      $(".updown").text('u25BC');
    }
    if ($(this).next(".accordion_body").is(':visible')) {
      $(this).next(".accordion_body").slideUp(300);
      $(this).children(".updown").text('u25BC');
    } else {
      $(this).next(".accordion_body").slideDown(300);
      $(this).children(".updown").text('u25B2');
    }
  });
});

.accordion_container {
  width: 100%;
  padding: 1em;
}

.accordion_head {
  background-color: #FFF;
  color: #555;
  cursor: pointer;
  font-family: arial;
  font-size: 14px;
  margin: 10px 0 0px 0px;
  padding: 10px 11px;
  font-weight: bold;
  border: 1px solid #ddd;
}

.accordion_body {
  background: #EEE;
  padding: 1em;
}

.accordion_body p {
  padding: 18px 5px;
  margin: 0px;
}

.check-mark, .question-mark {
  border-style: solid;
  border-width: 1px;
  border-radius: 50%;
  float: right;
  height: 28px;
  line-height: 16px;
  padding: 5px;
  position: relative;
  width: 28px;
  text-align: center;
  top: -4px !important;
}

.check-mark {
  border-color: #c4db30;
  color: #c4db30;
}

.question-mark {
  border-color: #086cff;
  color: #086cff;
  font-size: 1.3em;
}

.plusminus {
  float: left;
  margin-right: 10px;
}

Here’s where I’m stuck.

Once I select an answer for a question, I want the accordion to collapse to the next question, of course, it will only apply to single answer fields.

1. How do I expand the next question after I select an answer for the previous question?
2. How do I change the question mark to a check mark after I select an answer?

Answer

You can surround each “accordion” with a div (i gave it a class accordion_main)

add the check mark classes and remove the question class.

The html will look like this:

<div class="accordion_main">
                    <div class="accordion_head"><span class="updown">▼</span> What type of sensors are required? <span class="glyphicon glyphicon-ok check-mark" aria-hidden="true"></span> 
                    </div>
                    <div class="accordion_body" style="display: block;">
                        <select>
                            <option value="sensors">None Selected</option>
                            <option value="sensors">Photocell On</option>
                            <option value="sensors">Off Control Only</option>
                            <option value="sensors">Photocell On / Off Control Only</option>
                        </select>
                    </div>
                </div>

and js:

$(document).ready(function () {

$(".accordion_head").click(function () {
    if ($('.accordion_body').is(':visible')) {
        $(".accordion_body").slideUp(300);
        $(".updown").text('u25BC');
    }
    if ($(this).next(".accordion_body").is(':visible')) {
        $(this).next(".accordion_body").slideUp(300);
        $(this).children(".updown").text('u25BC');
    } else {
        $(this).next(".accordion_body").slideDown(300);
        $(this).children(".updown").text('u25B2');
    }
});
$(".accordion_body select").change(function () {
    nextQuestion($(this));
});
$(".accordion_body input").change(function () {
    nextQuestion($(this));
});
});

function nextQuestion(currentQuestion) {
    var parentEle = currentQuestion.parents(".accordion_main");
    if (parentEle.next()) {
        parentEle.find(".question-mark").addClass("glyphicon glyphicon-ok check-mark").removeClass("question-mark").text("");
        if (currentQuestion.attr('type') != 'checkbox') {
            if (parentEle.next().find(".accordion_head").length > 0) {
                parentEle.next().find(".accordion_head").click();
            } else {
                //there is no next--> try to go to the next colum
                parentEle.parent("div").next("div").find(".accordion_head").first().click();
            }
        }

    }
}
