Hello,
There are many ways to achieve that. Here are two of them:
1) Take advantage of the
Visual Inheritance in Kentico and specify different templates with different configuration for each of your section, so the architecture would be Master page (for instance header and footer) -> Menu template (your menu) -> Content template (individual templates for actual content)
2) You can add three different menus next to each other into one template (probably on the master page) and hide those two if the current location doesn't match your specification, so only one menu is visible at the time
Best regards,
Jan Hermann
