Kivy label multiline text

Question

I want to make a program that has input some letters and it gives in real time all the combinations of words but i can display only a few because i can't figure out how to use multiline.I haven't used kivy for a very long time. Can anyone help me please?

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.label import Label
from kivy.uix.textinput import TextInput
from kivy.uix.button import Button
from kivy.uix.floatlayout import FloatLayout
import itertools



class Screen(BoxLayout):  

    def __init__(self, **kwargs ):
        super(Screen, self).__init__(**kwargs)
        self.orientation = "vertical"
        cuvinte = " "
        boxlayout2 = BoxLayout()
        button = Button()
        txt_instructions = Label(text = "Introduce your letters without any spaces between them")
        self.add_widget(txt_instructions)
        my_user_input = TextInput()
        boxlayout2.add_widget(my_user_input)
        self.add_widget(boxlayout2)   
        my_output = Label(halign = 'center')        
        self.add_widget(my_output)
        def callback(instance, value):
            cuvinte = " "
            lista2 = []
            lista3 = []
            n = value
            lista = list(n)
            for i in range(len(lista)):
                for word in itertools.permutations(lista):
                    lista2.append(''.join(word[0:len(word)-i]))

            for i in lista2:
                if i not in lista3:
                    lista3.append(i)
            lista3.sort()
            cuvinte = ' '.join(str(e) for e in lista3)
            my_output.text = cuvinte

        my_user_input.bind(text=callback)

Add multiline=True in your TextInput widget

my_user_input = TextInput(multiline=True)
