Certainly.

Can I have a STL list of lists?

Yep. The STL containers can store any data type, and other containers
are (at least for this purpose) no different from any other data type.

A few typedefs might make the resulting code easier to follow:

typedef std::list<mydata> my_data_list;

void foo(std::list<my_data_list> list_of_lists)
{
/*Do stuff with each list contained list_of_lists*/
}

(For more fun, you can also have, f'rexample, sets of maps of vectors.
typedef gets a *lot* more useful there.)

Can I have a STL list of lists?

Sure.

std::list<std::list<int> > listoflists;

When 'nesting' the angle brackets like this,
be sure to separate them by whitespace, else
the compiler will think they're a shift operator,
and generate an error.

Sure.

std::list<std::list<int> > listoflists;

Important point!
