Hi

I have a nested ordered list.

<ol>
  <li>first</li>
  <li>second
  <ol>
    <li>second nested first element</li>
    <li>second nested secondelement</li>
    <li>second nested thirdelement</li>
  </ol>
  </li>
  <li>third</li>
  <li>fourth</li>
</ol>

Currently the nested elements start back from 1 again, e.g.

1. first
2. second
   1. second nested first element
   2. second nested second element
   3. second nested third element
3. third
4. fourth

What I want is for the second element to be numbered like this:

1. first

2. second

   2.1. second nested first element

   2.2. second nested second element

   2.3. second nested third element

3. third
4. fourth

Is there a way of doing this?

Thanks
