Valid lists inside lists - ul inside ul

Question

I need lists inside lists.

What is the most correct way?

<ul> <li> <ul> <li><h2>title</h2></li> <li>element</li> <li>element</li> </ul> </li> <li> <ul> <li><h2>title</h2></li> <li>element</li> <li>element</li> </ul> </li> 

Will it really be? And semantic?

Answer 1

VALID , except that your second <h2> must be in <li> . You can invest as many as you want.
