Hi Tom,
I have a few comments. Let me know if you want to discuss them.

@xpl-odoo I made the changes based on what we discussed :) I'm still not super sure about the section on mega menus, especially the part about adapting the options and layout. I thought it would be useful to keep concrete examples of what you can do, but what do you think?
Also, I wasn't sure how we should refer to 'the Customize tab in the website builder'; this is the actual wording I used, but I'm not 100% convinced: should we just say "in the website builder" or "in the Customize tab", or something else?
Anyways, let me know what you think :)

@toaa-odoo @auva-odoo because this PR has multiple commits, I need to know how to merge it:

• merge to merge directly, using the PR as merge commit message
• rebase-merge to rebase and merge, using the PR as merge commit message
• rebase-ff to rebase and fast-forward
