Hello,

This isn’t possible in theme options but you can use this code to hide megamenu columns:

nav .codeless_custom_menu_mega_menu ul>li h6, .menu-small ul.menu .codeless_custom_menu_mega_menu h6, .menu-small ul.menu > li > a {

display: none;
}

Can you show us your site url so I can give you the specific cs code to center the button?

Best regards!

Hello,

Please use this css code for header button alignment.

.header_button {
margin-top: -22px;
}

Best regards!
