Just to be clear, you want to replace the buttons in the example below with Spinners?

The KV code below will behave more like a traditional menu, where the menu title item is what is always shown. Another alternative is to look at the Actionbar widget: https://kivy.org/doc/stable/api-kivy.uix.actionbar.html

What is the effect you are looking to achieve?
Why a FloatLayout? I typically only use a FloatLayout for special cases where I need to position on object on top of another.

Try putting everything below the canvas in a BoxLayout.
