How Can I Remove BoxLayout?

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)

YES.
When I make those changes;
Kv
SecondPage:
Calculation:
id:scd
speca:
id: speca
py
def on_state():
self.ids.scd.remove_widget(self.ids.speca)
It works.

How can I change the height of Boxlayout Dynamically?

I am trying to change Boxlayout height dynamically. There will an empty Boxlayout at the beginning, then with a ToggleButton I will add Buttons on that Boxlayout vertically. But this Boxlayout locates in Gridlayout which has ScrollView. And the number of buttons I will add will change, so the height of the box layout should change too. But it doesn't change. Could you please help.
Here is my main.py:
from kivy.app import App

from kivy.properties import ListProperty
from collections import OrderedDict
data1=["mother","father","son"]
data2=["uncle","aunt","grandfather"]
data3=["jack","mike","simon"]
data4=["1898","1975","1985","1885"]
class MainWidget(Widget):
an0=tuple(list(OrderedDict.fromkeys(data1)))
cal5= ObjectProperty()
def btn10(self,text):
if self.cal5:
self.cal5.parent.remove_widget(self.cal5) #EVERY TIME I NEED TO REMOVE IT BECAUSE MY BUTTON QUANTITIY AND TEXT WILL CHANGE DUE TO TOGGLE BUTTON SELECTION
self.cal5 =ModelSpecifications()
a=data2
b=data3
c=data4
mi=[]
n=0
while n < len(a):
aba=(str(a[n])+"\n"+str(b[n])+"\n"+str(c[n]))
mi.append(aba)
n+=1
for i in mi:
self.b1=Button(text=str(i),size_hint=(1,None),height="10dp")
self.cal5.add_widget(self.b1)
self.ids.scd.add_widget(self.cal5, index=3) #I ADD THE BUTTONS IN HERE
class SecondPage(ScrollView):
pass
some_number=120
calculated_height=(str(some_number)+"dp") #<------I CAN CHANGE THE HEIGHT AT THE BEGINING BUT IT DOSENT CHANGE THE HEIGHT DYNAMICALLY
class ModelSpecifications(BoxLayout):
def __init__(self, **kwargs):
super().__init__(**kwargs)
self.size_hint=(1,None)
self.height=calculated_height
class Calculation(GridLayout):

I am a beginner.
When I practicing screen switch and navigation drawer, I was expected that navigation drawer would runed as an example, which is https://kivymd.readthedocs.io/en/0.104.0/components/navigation-drawer/index.html.
When I run the code, I was confused with a problem, which was that
lambda x: nav_drawer.set_state("open") perhaps executed twice.

You can remove one MDNavigationDrawer or you can use my code:
try:
from jnius import autoclass
python_activity = autoclass('org.kivy.android.PythonActivity')
python_activity.removeLoadingScreen()
except:
pass
try:
import plyer
except:
pass

Python : How to get value of dynmaic row

I am new to python and kivy.
I am trying to get value of dynamic row.But now i am getting value like this
Column2
Column1
Can someone tell me how to get value like this ?
1,column1,column2
2,column1,column2
Because i have three column in my database table like id,name,value and i want to insert value in database table through loop
I am using this code
def insert_value(self):

values.append(ch.text)

for x in range(0, lenArray):

To maintain a structure we must create a list of lists, then in each list the first parameter is the text of the Button that we filter through isinstance(), and the other elements are concatenated.

if isinstance(ch, TextInput):
vals.append(ch.text)
if isinstance(ch, Button):
vals.insert(0, ch.text)
values.append(vals)
for val in values:
print("{},{},{}".format(*val))

One option is to add a ListProperty to your Row class that stores the values of the row in the order you want, which makes it easier to obtain them later.
You can use a ListView to show the rows.

TextInput:

text:"Column2"
size_hint_x: .8
<Rows>:
