Hide static_front_page from customize options

You’ll want to look over the documentation for the Customizer API (http://codex.ww.wp.xz.cn/Theme_Customization_API), but as I recall there is an undocumented remove_section method:

$wp_customize->remove_section('static_front_page');

That line of code on it’s own will not do anything, it has be used in the proper context – specifically via the customize_register action:

add_action( 'customize_register', 'gowp_customize_register', 999 );
function gowp_customize_register( $wp_customize ) {
  $wp_customize->remove_section( $section );
}
