I am creating onepage site layout for wordpress theme for that i added dropdown-pages under wp-customizer. I want to know if it is possible to make dropdown-pages drag-drop able…

i am unable to set templates for them

below is the image of dropdown-pages and php code i used to call these pages, but

If it is possible to make “dropdown-pages” drag able, it will be easier to set templates for each page

<?php

    $page1 = get_theme_mod( 'icona_dropdownpages_setting_1', '' );
    $page2 = get_theme_mod( 'icona_dropdownpages_setting_2', '' );
    $page3 = get_theme_mod( 'icona_dropdownpages_setting_3', '' );
    $page4 = get_theme_mod( 'icona_dropdownpages_setting_4', '' );
    $page5 = get_theme_mod( 'icona_dropdownpages_setting_5', '' );
    $page6 = get_theme_mod( 'icona_dropdownpages_setting_6', '' );
    $page7 = get_theme_mod( 'icona_dropdownpages_setting_7', '' );
    $page8 = get_theme_mod( 'icona_dropdownpages_setting_8', '' );

    $oneargs = array(
        'post_type' => 'any',
        'posts_per_page' => '-1',
        'post__in' => array( $page1, $page2, $page3, $page4, $page5, $page6, $page7, $page8 ),
        'orderby' => 'post__in',
        );
        
    $onequery = new WP_Query( $oneargs );
    
    if( $onequery -> have_posts() ):
        
        while (  $onequery -> have_posts() ): $onequery -> the_post();
        
            get_template_part('template-parts/content', 'onepage');
        
        endwhile;
        
    endif;
    
?>
