i using multitab in kivy. how enlarge scrollbar scrollbar can moved(up_down) mouse. using boxlayout , recycleview. code below working gridlayout, not in boxlayout:

layout.bind(minimum_height=layout.setter('height'))

enter image description here here example of how extend scrollview dragable slider.

from kivy.app import app kivy.uix.boxlayout import boxlayout kivy.lang import builder kivy.uix.label import label  builder.load_string(""" <scrollslider>:     scrollview:         id: scrlvw         bar_width: 0         gridlayout:             id: grid             size_hint_y:none             cols:1             height: self.minimum_height             scroll_y: slider.value             on_touch_move: slider.value = self.scroll_y     slider:         size_hint_x: none         width: root.width*0.2         id: slider         min: 0         max: 1         orientation: 'vertical'         value: scrlvw.scroll_y         on_value: scrlvw.scroll_y = self.value  """)   class scrollslider(boxlayout):      def custom_add(self, widget):         self.ids.grid.add_widget(widget)  class myapp(app):       def build(self):         scrollslider = scrollslider()         in range(1, 100):             scrollslider.custom_add(label(text=str(i), height=100, size_hint_y=none))         return scrollslider  if __name__ == '__main__':     myapp().run()

you need use custom_add add widgets in scrollslider or add them gridlayout in kivy.

i took inspiration link @edvardas dlugauskas provided.

the code provided not work boxlayout because boxlayout takes size of parent. able scroll need add sth scrollview larger scrollview itself.
