Hi Azhar,

I suggest you to add this JS snippet to add support for custom URLs in tabsets:

jQuery( 'body' ).on( 'click', '.nav-tabs li a', function( ev ) {
    var $a = jQuery( this );
    
    if ( $a.attr( 'href' ).match( /^https?/ ) ) {
        window.location.href = $a.attr( 'href' );
        return false;
    }
} );
