python - How to create a nasted widget based on selecting a choice from a dropdown in jupyter lab/ipywidgets?

Question

How to generate a widget based on selecting an option from a dropdown menu? I have an example code is given below?

from ipywidgets import *
x = Dropdown(options=['a', 'b'])
#y = Dropdown(options=['1', '2'])
 
x.observe(change_x, 'value')

HBox([x])

For example, based on selecting 'a' It should create and display a second drop-down menu 'y' and on selecting 'b' It should create and display a text box.

Thank you.
