Hi Olivier,
You have to make a menu for NL, FR AND EN. So Home-NL, Home-EN, Home-FR.
Afther that you create a templatestyle Home-NL, Home-EN AND Home-FR. In these style you select frontpage layout and under the menu settings you choose the NL, EN or FR menu. (these styles do you assign to Homepage for NL, EN and FR)
Than you create another tree menu’s for the other pages. So website-NL, website-EN and website-FR. Under menu you choose the correct menu. and you assign these to the other pages off the language.
I hope you understand it ? Let me hear.
Good luck
Kind Regards,
Mike Ronday
