                  height:self.minimum_height
                  #size_hint: 1, 1
                  TextInput:

                      id: notes
                      color: 1,1,1
          BoxLayout:
              size_hint: .15, 1

  <p>with the above codes, i got the fist picture. although when i start typing, the textinput space extends and once it get to the maximum size, the scroll effect is activated. how do i make the textinput to be in the maximum size from start?</p>
