Using th:each on an unordered list of list items : ive tried this a variety of ways but I cant get it to work...

every example of th:each ive seen used, was initiated on a div, which the sample code in this question does not contain....does anyone know the way to implement this while appeasing the code sample in the question

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>
      <li th:each="contact : ${contacts}">
        th:text=${contact.firstName} 
      </li>
    </ul>
  </body>
</html>

I thought it is better policy to write "th:each" in parent <ul> element.

But apparently Chris has a different opinion for that

This below should work:

    <ul> <!-- REPLACE THE LI ELEMENTS BELOW -->
      <li th:each="contact:${contacts}" th:text="${contact.firstName}"></li>
    </ul>

For the previous video, there is the same question that you asked. Check it out. Here is the link.

Yes...the old style is another variation i tried...but it returns the following error:

Bummer! You are missing a th:each attribute in your <li>. This is required for Thymeleaf to generate multiple elements based on a collection.

Oh. I'm sorry for misleading with GitHub. I thought you were having problems with project, but it was just a challenge.
