How to change items in the form with changing items in a selectbox?

How to change items in the form with changing items in a selectbox ?
for example when i change private to busuness, then automatically the next text lable change.

import streamlit as st

st.title(‘Registration form’)

with st.form(“my_form”):

st.subheader('Customer information')
ct = ['Private','Business']
ctype = st.selectbox('Customer type', ct)

if ctype == 'Private' :
    cname = st.text_input('Name and family name')
else:
    company = st.text_input('Company name')

submitted = st.form_su

Because st.form is designed to not register any changes until you press the submit button, the easiest solution is to not put things in a form. For example:

import streamlit as st

st.title("Registration form")

st.subheader("Customer information")
ct = ["Private", "Business"]
ctype = st.selectbox("Customer type", ct)

if ctype == "Private":
    cname = st.text_input("Name and family name")
else:
    company = st.text_input("Company name")

submitted = st.button("Submit")

if submitted:
