menu at bottom of slider / featured image

@mosign: It would have been easy for me to explain if you had your site live. So, I could check in your slider and featured image. Also, you shouldn’t edit any core theme files such as header.php, index.php, functions.php, style.css and so on which are inside catch-responsive theme directory. As all these edits will be reverted back to original when you update or upgrade your theme.

If you want to edit any core theme files then you need to build child theme and edit it. For child theme, check out http://catchthemes.com/blog/create-child-theme-wordpress/. You can download sample child theme from there and then add the following code in your child theme functions.php file.

// Unhook default Catch Responsive functions
function unhook_catchresponsive_functions() {
    remove_action( 'catchresponsive_after_header', 'catchresponsive_primary_menu', 20 );
}
add_action( 'init', 'unhook_catchresponsive_functions' );

//Adding menu after slider
add_action( 'catchresponsive_before_content', 'catchresponsive_primary_menu', 20 );

@mosign: Yes, for Catch Responsive Pro you can use http://catchthemes.com/support-forum/forum/catch-responsive-pro-premium/. But to change menu position, you can use the same code as below in Catch Responsive Pro child theme.
