Try going to the What's On page and creating a new page there, so that it appears under the What's On page in the Site Map.

You can find out all about Includelets in the documentation. I recommend reading through all the sections of the Getting Started helpsheet and understanding the different bits, even if you don't actually do them on your site.

You can find out more about includelets in the CMS section of the documentation.

You could join us in the next User Group Zoom chat on the 12th March, where I can demo adding pages and creating a dropdown nav menu. More info on the Voice Users website.

Thanks
