Try something like this (pseudo-code in some places):

foreach ($styles as $foo) // iterates through each set of sub-arrays in the 
array
{
    echo <select name="$foo[$key];
    $arraylen = count($foo); // checks size of the current sub-array
    for($i = 0; $i < $arraylen; $i++)
      { // iterates through each entry within the sub-array
      echo <option name="$foo[$i]">$foo[$i]</option> // writes your option 
statement
      }
    echo </select>;
}

Might be a bit rough around the edges but that's the gist of it.

FYI, I don't think what you've got is called a two-dimensional array, it's 
a multi-dimensional array.
