Hi,

In Odoo, this isn’t something you can fully achieve from standard settings alone.

    Vertical menu: Odoo’s default website menu is horizontal. To make it vertical, the easiest and most practical approach is to use a theme module that supports vertical/side navigation. Otherwise, you’d need custom CSS/JS changes.

    Footer with 10 columns: You can do this from the Website Builder by:

        Editing the footer

        Adding a grid/columns block

        Setting it to 10 columns and placing one link in each

        (or customize with CSS if your theme limits column count)

Hope it helps
