Challenge requiring me to enter th:each in <li> instead of <ul>

To repeat the list, I should be entering the th:each in the ul element. But its failing saying I need to enter it in the li element. For the li element to repeat, I need to code it like below. What am I doing wrong?

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
  <head>
    <meta charset="UTF-8"/>
    <meta description="viewport" content="width=device-width, initial-scale=1"/>

    <link rel="stylesheet" th:href="@{/app.css}"/>

    <title>Contact List</title>
  </head>
  <body>
    <h1>Contacts</h1>
    <ul th:each="contact : ${contacts}"> <!-- REPLACE THE LI ELEMENTS BELOW -->
      <li th:text="${contact.firstname}">

      </li>
    </ul>
  </body>
</html>
src/main/resources/templates/contact_list.html 
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
  <head>
    <meta charset="UTF-8"/>
    <meta description="viewport" content="width=device-width, initial-scale=1"/>

    <link rel="stylesheet" th:href="@{/app.css}"/>

    <title>Contact List</title>
  </head>
  <body>
    <h1>Contacts</h1>
    <ul th:each="contact : ${contacts}"> <!-- REPLACE THE LI ELEMENTS BELOW -->
      <li th:text="${contact.firstname}">

      </li>
    </ul>
  </body>
</html>

Hi

If you want to generate list items you shoud put the th:each inside the <li> element, otherwise you wouldn't be filling your list but creating a new list with a single item everytime.

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
  <head>
    <meta charset="UTF-8"/>
    <meta description="viewport" content="width=device-width, initial-scale=1"/>

    <link rel="stylesheet" th:href="@{/app.css}"/>

    <title>Contact List</title>
  </head>
  <body>
    <h1>Contacts</h1>
    <ul> <!-- REPLACE THE LI ELEMENTS BELOW -->
      <li th:each="contact : ${contacts}" th:text="${contact.firstName}">name</li>

    </ul>
  </body>
</html>
