The function myplugin_options_page will register the admin page and the myplugin_render_options_page function will rendering the admin page. These functions could be useful for admin information or with a bit more work you can easily enhance these functions to be part of your website options.

Add these two functions on your theme’s functions.php or create a plugin.

function ns_options_page(){

  // add top level menu page
  add_menu_page(
    'Options Page',
    'Options Page Title',
    'manage_options',
    'myplugin-options',
    'myplugin_render_options_page'
    );
  }
  
add_action('admin_menu', 'ns_options_page');

function ns_render_options_page() {

 if (!current_user_can('manage_options')) {
    return;
  } ?>
    <div class="wrap">
      <h1><?php echo esc_html(get_admin_page_title()); ?></h1>
      <p>Page content goes here</p>
    </div>
  <?php
}
