Hey Jörg,
Thank you for the link to your site, your main menu items are all anchor links for the homepage and are all linked with only the ID, like this:

which is good for a single page site, which yours mostly is, but for the few additional pages you have like your privacy page these menu items need to be the full URL so they link back to the homepage. But changing all of your anchor links to the full URL will cause your menu anchor highlighting to also change, which you don’t want.
So I wrote this script for your three pages: Datenschutz, Impressum, & Datenschutzerklärung to redirct back to the home page when the main menu links are clicked.

function custom_script() { ?>
    <script>
(function($){
$(".page-id-399 #avia-menu .menu-item-type-custom a,.page-id-397 #avia-menu .menu-item-type-custom a,.page-id-632 #avia-menu .menu-item-type-custom a").click(function() {
   var hostname = 'https://your-domain.com/';
   var $this = $(this);       
   var _href = $this.attr("href"); 
   var hash = _href.substring(1, _href.length);
   $this.attr("href", hostname + "#" + hash);
}); 
})(jQuery);
</script>
    <?php
}
add_action('wp_footer', 'custom_script');

I added this to your child theme functions.php, please check.

Best regards,
Mike

Hi,
Vielen Dank für Ihre Geduld. Soweit ich weiß, möchten Sie, dass alle Texte und Zellen dieselbe Farbe haben. Bitte versuchen Sie diesen Code im Feld General Styling ▸ Quick CSS oder in das Feld WordPress ▸ Anpassen ▸ Zusätzliches CSS:

#top #main .main_color .pricing-table>li:nth-child(even) {
    color: #000;
}
#top #main .main_color .pricing-table>li:nth-child(odd) {
	background: #fff;
}

Nachdem Sie das CSS angewendet haben, leeren Sie bitte Ihren Browser-Cache und überprüfen Sie es.

Thank you for your patience, as I understand you want all of the text & cells the same color, please try this code in the General Styling ▸ Quick CSS field or in the WordPress ▸ Customize ▸ Additional CSS field:

#top #main .main_color .pricing-table>li:nth-child(even) {
    color: #000;
}
#top #main .main_color .pricing-table>li:nth-child(odd) {
	background: #fff;
}

After applying the css, please clear your browser cache and check.

Hi,
Thank you for the login, this was caused by the last css rule in your Quick CSS, I commented it out to correct.

.html_header_top.html_header_sticky #main {
    padding-top: 46px !important;
}

Please clear your browser cache and check.

Hi,
Thanks for the links to the examples, to create 4 columns in the mega menu like our demo, please folow the steps in our documentation for: Create submenu rows and columns and use the dash (-) to create columns without headings:

here is how the mega menu looks with the 4 columns:

Best regards,
Mike

Hey tvbuzz,
I assume that you are trying to create a menu link to an ID anchor on your page, if so then your ID should be the href and not an ID of the menu item.
So you should create a custom menu item like this:

Please note that ID’s can not start with a number, so your options are using text like #xyz or like #one23

Best regards,
Mike
