title: Latex: How can I create nested lists which look this 1.1, 1.1.1, 1.1.2, 1.2
body: <p>How can I create lists which look this:</p>
  
  <pre>
  1. Topic
  1.1 First Subtopic
  1.2 Second Subtopic
  </pre>
  
  <p>I tried using the enumeration list</p>
  
  <pre><code>\begin{enumerate}
  \item Topic
  \begin{enumerate}
  \item First Subtopic
  \item Second Subtopic
  \end{enumerate}
  \end{enumerate}
  </code></pre>
  
  <p>But the output looks like:</p>
  
  <pre>
  1. Topic
    (a) First Subtopic
    (b) Second Subtopic
  </pre>
  
  <p>So how can I get the list? Is there another list evironment or maybe an extra package?</p>
