Hi

Thanks for contacting us. You can use this CSS in your custom.css file

div#sp-menu {
    display: flex !important;
    justify-content: flex-start;
    align-items: flex-start;
}

#sp-header a {
    font-size: 16px !important;
}

-Regards.

Ineed like this pic

move the main menu to start from the right

Means move from left to right side.

as I saw you have right align now in menu container.

In you want to increase menu column width coresponding to component content area you have to use also that Custom CSS:

@media (min-width: 1400px) {
 #sp-header > .container {max-width: 1320px;}
}

and you will get the same container width menu and component content :)
