Hi,

Welcome to the Optimizely Community!

I think the best thing to do is explore the code base and get familiar with the architecture and folder layout as this helps to find areas in the solution. Remember the foundation project is for guidance.

To help you get up and running hopefully this will help:

1. Menu items are defined in a 'LayoutSettings' page within the CMS. Look in the tree navigation and you should see something like 'Settings'. Once you have found this page then there is a property 'MainMenu' this is where you can add some items to the menu. Really you can build a menu however you like this is one-way. You can traverse the page treee and pull out the items you wish and build a navigation that way or implement you own architecture.
2. there a number of partial / components that build out the navigation render, start with the layouts '_MasterLayout','_Layout' and then work your way down too '_Header','_Navigation','_Menu'.
3. Widgets to me sound like re-useable functionality across the site Optimizely uses a concept called 'blocks' and this would be the same I believe as widgets.

If you need more help I would advise either the optimizely documenation, start with 'Content Management System' and learn as much as you can. Additionaly there is some courses on the optimizely academy  that will also help learn the platform.

Thanks

Thanks Paul for that info. I'm sure different developers with varying background and experience will have unique encounters with the Foundation and Mosey samples. The code looks great in both of them, but I do see an opportunity for Optimizely or whoever created/architected them to possibly go on at some length in a white paper explaining the architecture and how everything works. There are good in-line comments but I'm talking overall. I'm gradually getting it but it would come faster with more tutilage (or documentation/training that accomplishes the same). I will have to look into the Academy you mentioned. Our account rep mentioned some official training, maybe the Academy is what they meant. I'm sure it will come together. The documention is fairly extensive but after spending some time reading through it seems a bit patchy and high-level in most places, combined with some samples that don't work (at least for me, like the one for creating and empty site:

URL https://docs.developers.optimizely.com/content-management-system/docs/creating-a-starter-project.)

Naturally after 10 years of Ektron I know it like the back of my hand so it is a big adjustment.
