menu con categorie prodotto sempre allineate orizzontalmente su una riga

Hey bassato,
It looks like there is enough room in your menu for more items, Please see the screenshot in the Private Content area.
Or do you mean at smaller screen sizes, if so you should make the mobile menu show until the desktop menu will fit on the screen, such as 1215px with this css:
Try this CSS in your Enfold Theme Options ▸ General Styling ▸ Quick CSS field:

@media only screen and (max-width: 1215px) {
  #top #header .av-main-nav > li.menu-item  {
      display: none!important;
  }
  #top #header .av-burger-menu-main {
      cursor: pointer;
      display: block!important;
  }
}

Please ensure to copy the code from the forum and not an email notification so the symbols are not converted.
After applying the css, please clear your browser cache and check.

Best regards,
Mike

Hi,
To move your account & search menu items next to the cart icon:

this is only needed for screens larger than 990px, because on mobile it’s already next to the burger menu:

Add this CSS in your Enfold Theme Options ▸ General Styling ▸ Quick CSS field:

@media only screen and (min-width: 990px) { 
.account-menu {
    position: absolute;
    z-index: 3;
    height: 46px;
    right: 0;
    width: 150px;
    line-height: 46px;
    text-decoration: none;
    text-align: center;
    top: 38%;
    margin: -23px 0 0 0;
}
.account-menu .cart_dropdown {
	top: 85%;
}
.account-menu #menu-item-wc-account-icon {
	display: inline-block;
    height: 46px;
    width: 46px;
    float: left;
}
.account-menu #menu-item-search {
	display: inline-block;
    height: 46px;
    width: 46px;
    float: left;
}
.account-menu .menu-item-account-icon a {
	line-height: 46px !important;
	width: 46px;
    height: 46px !important;
    display: inline-block;
}
.account-menu #menu-item-search a {
	line-height: 46px !important;
	width: 46px;
    height: 46px !important;
    display: inline-block;
}
}

Then add this code to the end of your child theme functions.php file in Appearance ▸ Editor:

function move_account_search_nexto_cart() { ?>
  <script>
window.addEventListener('DOMContentLoaded', function() {
(function($){
	var width = $(window).width();
	if ((width >= 990)) {
 $(".menu-item.cart_dropdown ").wrapAll("<span class=account-menu></span>");
 $('#avia-menu #menu-item-wc-account-icon').detach().insertBefore('.account-menu .cart_dropdown');
 $('#avia-menu #menu-item-search').detach().insertBefore('.account-menu .cart_dropdown');
	} else {}
})(jQuery);
});
</script>
  <?php
}
add_action('wp_footer', 'move_account_search_nexto_cart', 99);

this is the expected results:

Best regards,

Hi,
Try adding this css:

.account-menu {
	z-index: 3;
}

then clear your browser cache.

Hi,
When testing for different devices on your desktop browser you will need to reload the page when you chage the screen width, this will not be an issue for real devices because their screen sizes don’t change in the same way after page load.
Adding a listener to the page only for testing is not a good idea.

Hi,
On the page that you linked to I didn’t see your example, so here is a screenshot of the first item:

do you want the large 20,00 € + IVA to be small.
and the small 24,40 € to be large?
both can stay in their places, you just want the font size changed, correct?

Mike
