Master Detail Page on the right side using Xamarin.Forms

Try to create custom page with behavior similar to existing master detail page, with only one difference - opening from right side.
Custom class has two properties: Content and Menu - both Page type.
In custom renderer I use RendererFactory.GetRenderer to get renderer for each page and add NativeView as subviews. looks like this works, but only if I set size of each control in page.
Maybe, somebody has solution how to fix this issue?
