This is the code from the example. There is a kiwi markup here. But how to give this code functionality. For example, so that after canceling the checkbox, the item disappears from the list. I was able to achieve only to remove the icons. I tried adding the on_release function there, but it didn't solve the problem.

from kivy.lang import Builder
from kivy.properties import StringProperty

from kivymd.app import MDApp
from kivymd.uix.list import IRightBodyTouch, OneLineAvatarIconListItem
from kivymd.uix.selectioncontrol import MDCheckbox
from kivymd.icon_definitions import md_icons


KV = '''
<ListItemWithCheckbox>:

    IconLeftWidget:
        icon: root.icon

    RightCheckbox:


BoxLayout:

    ScrollView:

        MDList:
            id: scroll
'''


class ListItemWithCheckbox(OneLineAvatarIconListItem):
    '''Custom list item.'''

    icon = StringProperty("android")


class RightCheckbox(IRightBodyTouch, MDCheckbox):
    '''Custom right container.'''


class MainApp(MDApp):
    def build(self):
        return Builder.load_string(KV)

    def on_start(self):
        icons = list(md_icons.keys())
        for i in range(30):
            self.root.ids.scroll.add_widget(
                ListItemWithCheckbox(text=f"Item {i}", icon=icons[i])
            )


MainApp().run()

first you need to create a method to remove the widget from the scroll widget that will take the ListItemWithCheckbox instance and remove it from the list just link following

from kivy.lang import Builder
from kivy.properties import StringProperty

from kivymd.app import MDApp
from kivymd.uix.list import IRightBodyTouch, OneLineAvatarIconListItem
from kivymd.uix.selectioncontrol import MDCheckbox
from kivymd.icon_definitions import md_icons

KV = '''
<ListItemWithCheckbox>:

    IconLeftWidget:
        icon: root.icon

    RightCheckbox:
        # add this line that will call the remove widget when we change the check box state and will pass the 
        # ListItemWithCheckbox widget that will be removed from the list
        on_active:app.remove_widget(root)

BoxLayout:

    ScrollView:

        MDList:
            id: scroll
'''


class ListItemWithCheckbox(OneLineAvatarIconListItem):
    '''Custom list item.'''

    icon = StringProperty("android")


class RightCheckbox(IRightBodyTouch, MDCheckbox):
    '''Custom right container.'''


class App(MDApp):
    def build(self):
        return Builder.load_string(KV)

    # create method to remove list item
    def remove_widget(self, widget):
        print(widget.text)
        self.root.ids.scroll.remove_widget(widget)

    def on_start(self):
        icons = list(md_icons.keys())
        for i in range(30):
            self.root.ids.scroll.add_widget(
                ListItemWithCheckbox(text=f"Item {i}", icon=icons[i])
            )
