divide the menu in 2 parts on both sides of the logo

Hi there!

Thanks for your query.

It will be a customization work with any other template other than Indigo.

You have to create 2 menu and associated menu items. Create a custom Header with 3 columns and put logo position in the middle and then put your menu 1 in the menu position and you have to choose a different module position for your second menu to publish. Then the second menu would not look good, perhaps will appear as bullet pointed. So you have to style them using custom CSS.

In summery, it means you have to style your header by own as different templates has different styles by default. It is better to use Indigo if you like that header.

Hope you understands!

Best Regards
