Kivy Scrollview Is Not Working

I am trying to use kivy scrollview inside of EmployeeScreen class. it will not scroll!? what am I doing wrong? I hope this is not a duplicate, please help. I went to this link Kivy

Solution 1:

I was trying to use GridLayout in my .kv file, wrong, I had to create a class and override its init.

class MyLayout(GridLayout):
    def __init__(self,**kwargs):
        super(MyLayout,self).__init__(**kwargs)
        self.size_hint_y = (None)
        self.bind(minimum_height = self.setter('height'))

then I placed the class in the .kv file where GridLayout was.
