@AndrettiMilas, If you really need a top level menu item (which is not encouraged), you should use add_submenu_page
instead of add_options_page
. Please refer to the Codex for the required parameters.
You could add the submenu like:
add_submenu_page( 'wlseo', 'Submenu 1', 'Submenu 1', 'manage_options', 'wlseo-submenu-1')
;
