PySimpleGUI RELIEF_SUNKEN Expands When Items Marked Visible But Does Not Shrink When They Are Marked Not Visible

Question

I'm new to PYSimpleGUI and python GUI programming in general. I have made a simple settings relief that I'd like to have expand and contract as needed. Is there a way to get the 3rd picture to resemble the 1st once the elements have been marked visible then not visible?

When Program Starts

When Items Are Marked Visible

When Items Are Marked Not Visible

Picture 3 has the relief still expanded. Is there a way to have it contract again? Thank you!

Please see the code below:

import PySimpleGUI as sg

def mkWindow():
    # Layout for the Advanced relief
    layout = [
        [sg.Frame(layout=[
            [(sg.Text('Show Advanced Settings', size=[25, 1]))],
            [sg.Radio('No', "RADIO2", key='_radio_no2_', enable_events=True, default=True, size=(5,1)), sg.Radio('Yes', "RADIO2", enable_events=True, key='_radio_yes2_')],
            [(sg.Output(key='_out_', size=[25, 27], visible=False))]], title='Advanced',title_color='red', relief=sg.RELIEF_SUNKEN)]]

    window = sg.Window('Output Test', layout, finalize=True)

    while True:
        event, wvalues = window.read()
        if(event=='_radio_yes2_'):
            window.Element('_out_').Update(visible=True)
            
        if(event=='_radio_no2_'):
            window.Element('_out_').Update(visible=False)

        if(event==sg.WIN_CLOSED):
            break

    window.close()

mkWindow()

Edited to add code. I pared it down to be just the affected frame that still produces the effect when the GUI is generated.

add some code so we can check the code. – Bhargav Desai Jul 27 '20 at 05:22 — Bhargav Desai, Jul 27 '20 at 05:22
Just added it. Thank you for the suggestion. – user13991063 Jul 27 '20 at 13:28 — user13991063, Jul 27 '20 at 13:28

It really is all in the docs. There is a pin function that does exactly what I was looking for. If added within any kind of frame, the frame auto-sizes as expected. I believe it does shift things within the collapse function by just a bit because it's a layout element within a larger layout, but I got around this by putting the other elements together in another element so they aligned ok. Hope this helps someone out there.

Cookbook where I got the relevant code.

Code for convenience/in case link breaks at some point:

import PySimpleGUI as sg

Demo - "Collapsible" sections of windows

This demo shows one techinique for creating a collapsible section (Column) within your window.

It uses the "pin" function so you'll need version 4.28.0+

A number of "shortcut aliases" are used in the layouts to compact things a bit.
In case you've not encountered these shortcuts, the meaning are:
B = Button, T = Text, I = Input = InputText, k = key
Also, both methods for specifying Button colors were used (tuple / single string)
Section #2 uses them the most to show you what it's like to use more compact names.

To open/close a section, click on the arrow or name of the section.
Section 2 can also be controlled using the checkbox at the top of the window just to
show that there are multiple way to trigger events such as these.
