body: <p>Say if I have an ArrayList with user objects into it. </p>
  
  <p>User.java</p>
  
  <pre><code>class User{
    private Long id;
    private String name;
  }
  </code></pre>
  
  <p>I have a list with users</p>
  
  <pre><code>list.add(new User(1,"John");
  list.add(new User(2,"Sam");
  </code></pre>
  
  <p>I want to check in thymeleaf if user List is having a user with name "Sam".</p>
  
  <pre><code>${#lists.contains(userList.name,'Sam')}
  </code></pre>
