With Crocal, you can have easily a one-page site. To create such a site please do as follows.
- Add Section IDs (e.g., idname1) in Rows you want to use in your menu.
- Create a menu with the usual way (Appearance > Menus).
- Add as menu items the custom links you need. For example, http://www.site.com/pagename/#idname1
- Save the menu and use it by selecting it from Appearance > Menus in the Header Position or from the Page Options > Header / Main Menu > Main Navigation Menu of the page.
In the exact same way, you can create one such menu for the Anchor Menu.
Set the Home Button in One-Page version
You can set a home button (with the behaviour of the back-to-top button) by creating a custom link with the following URL: #eut-goto-header.
