Your state can be a tree, if it needs to be, so you can nest.

A normal practice is to have a model per page. For e.g. https://github.com/rtfeldman/elm-spa-example/blob/master/src...

And you can have another item next to it for global state if you need to. https://github.com/ohanhi/elm-shared-state explains one way to do this
