Basic feedback forms

You must complete several steps to create your own feedback form:

Create an HTML document that will contain the required fields. Add CSS styles. By using the “JavaScript method”, you will be able to send data from the form. You upload the created form to any hosting that supports the HTTPS protocoland add a link to the form in the administration interface.

We recommend creating an output form using the web application for simplicity and clarity.

Create a custom output form that contains feedback text and allows you to send a conversation transcript to email.

JavaScript code of our example

Upload a form to any hosting

In our case, click the Save button first, then export to .zip format (see instructions below).

We have a form ready, now you need to upload the form to the internet so we can refer to it from the administration interface. In our case, we will use the GitHub site. You can find more information here.

If you use a tool other than, the form code will look like this:

<!DOCTYPE html>
    <meta charset="UTF-8">
    <link rel='stylesheet prefetch' href=''>
    <style type="text/css">
      html, body {
        width: 100%;
        height: 100%;
        background-color: transparent;
      .vertical-align-middle {
        display: flex;
        width: 100%;
        height: 100%;
        justify-content: center;
        align-items: center;
      .my-form {
        width: 100%;
        max-height: 100%;
        overflow: auto;
        padding: 1rem;
      .form-control, .btn {
        border-radius: 8px;
      .btn[type="submit"] {
        background-color: #39A2EF; /* Barva talčítka */
        color: white; /* Barva textu tlačítka */

    <div class="vertical-align-middle">
      <form id="my_form" class="my-form">
        <div class="form-group">
          <label for="content">Vaše zpětná vazba</label>
          <textarea class="form-control" id="content" rows="3"></textarea>
        <div class="form-check form-check-inline">
          <label class="form-check-label">
            <input class="form-check-input" type="checkbox" id="send_to_email">
            Odeslat přepis chatu na e-mail
        <div class="form-group">
          <input type="email" class="form-control email" id="email" placeholder="E-mail" disabled>
        <button type="submit" class="btn btn-info btn-block">Odeslat</button>

    <script src=''></script>
    <script src=''></script>
    <script src=''></script>
    <script type="text/javascript">
      var checkbox = document.getElementById('send_to_email');
      var form = document.getElementById('my_form');

      checkbox.onchange = function (e) {
        document.getElementById('email').disabled = !;

      form.onsubmit = function (e) {

        var content = document.getElementById('content').value;
        var email = document.getElementById('email').value;
        var checked = document.getElementById('send_to_email').checked;

          type: "FEEDBACK_ACTION",
          email: checked ? email : null,
          stars: null,
          content: content
        }, "*");

The last step

You created an entry form using We then exported it to our computer. We have uploaded the exported folders to the GitHub repository and then switched on the GitHub site. So we have a link to our form that we put into the administration interface.
