I want to remove a Boxlayout in my widget, but I cant.
There is a Boxlayout at the begining of the app called "Speca". After my sellections it must be removed.
When you run the app, sellect something in "Home" Spinner and click any of the new Toggle buttons.
Wtih the press of any of the Toggle buttons "Speca" must disappear.
Please help.
Here is main.py:

Please run the app and see it.
Looks to me like speca is a child of the calculation widget with ID scd. So give speca an ID and then Remove speca via ids in on_srate python function.
Kv
SecondPage:
Calculation:
id:scd
speca:
id: speca
py
def on_state():
self.root.ids.scd.remove_widget(self.root.ids.speca)
