Great, stupid me for not thinking about it before.
Thanks, a kiss from Italy

Done

For example in the Italian language the preview of the search is correct —-> https://dropmefiles.com/WpNp

but if I press enter or click on the search button the page automatically goes to English ———> https://dropmefiles.com/j2aqp

and if I try to change the language to a 404 error —-> https://dropmefiles.com/WZNrt

I solved the problem with these css
.et-advance-tabs .et-tabs-nav {
font-size: 18px;
font-family: “Neuton”;
color: # f7f7f7;
background-color: # 080808;
}

.et-advance-tabs .et-tabs-nav> ul .et-tab-nav: hover, .et-advance-tabs .et-tabs-nav> ul .et-tab-nav.active, .et-advance -tabs .et-tabs-nav> ul .et-tab-nav.active-default {
font-size: 22px;
color: # f10c17;
}

but I don’t know if it is a correct procedure.

Hello,
I solved the problem with static blocks
Now I have another problem with mega menus.

If I load the static block, it is correct (the spacing between the menu items)

But loading it on the main menu of the header bottom as a mega menu, opening it, the spacing between the fields of the menu does not change.
