menu on top

There is no any option on theme to move the navigation. You can move it using CSS design. Use Child theme to customize theme.

Find and cut the below code from header.php and paste below the body_class(); of same file.

<div class="header">
                    <div class="header-inner">
                            <div class="logo">
                                    <a href="<?php echo esc_url( home_url('/')); ?>">
                                        <?php if( of_get_option( 'logo', true ) != '' ) { ; ?>
                                            <?php if( of_get_option('logo',true) == 1 ) { ?>
                                                <h1><?php bloginfo('name'); ?></h1>
                                            <?php } else { ?>
                                           <img src="<?php echo esc_url( of_get_option( 'logo', true )); ?>" / >
                                        <?php } } else { ?>
                                            <h1><?php bloginfo('name'); ?></h1>
                                        <?php } ?>
                                        <p><?php bloginfo('description'); ?></p>
                                    </a>
