Anchor links close popup layer problem

[Initiostar]

Curious to see if an anchor mobile menu could work with the pop-up closing: https://anchor.initiostar.co.uk. Works on my Android OK. Used a hamburger mouseover animation rather than a link to the pop-up layer with a background on the layer to keep the menu in view.

It scrolls between the anchors on a single page, but it you add additional pages to the menu, I could not get the additional pages to open at the top of page (despite using _top).

The mobile menu-page & mobile menu/mouseover mobile menu layer approaches work very well, so still trying to understand the application for anchor-driven menus? maybe a supersite with a table of content approach?

Happy to share the mobile menu models I have used so far (including the new fit to width option).
