I have a window to display multiple treeview widgets. Currently there are some empty row spaces below the treeview when I expand it and I'm not sure on how to fill the empty spaces below dynamically when I expand the window. I have tried adjusting the rowspan/columnspan options but could not get the desired output as described in image below. I have also included a reproduceable code below for testing my program. Please help to advise on which part I need to make changes. Thanks!

Issues found
- Wrong row number on
frame_checkpd.rowconfigure(2, weight=1), it should be row 1. - Wrong sticky option on
parentframe.grid(column=0, row=1, columnspan=3, sticky='W'), it should be 'NSEW'. - missing
parentframe.rowconfigure(...)andparentframe.columnconfigure(...) - missing
frame_tree.rowconfigure(...)andframe_tree.columnconfigure(...)
Below is the required changes to achieve it:
class tab_one(Frame):
def __init__(self, *args, **kwargs):
...
parentframe = tk.LabelFrame(frame_checkpd, bd=0)
frame_checkpd.rowconfigure(1, weight=1) ### row 2 -> 1
frame_checkpd.columnconfigure(2, weight=1, )
parentframe.grid(column=0, row=1, columnspan=3, sticky='NSEW') ### 'W' -> 'EW'
# PARENT TREE
parentframe.rowconfigure(1, weight=1) ### added
parentframe.columnconfigure(0, weight=1) ### added
...
# CHILD TREE
frame_tree.rowconfigure(0, weight=1) ### added
frame_tree.columnconfigure(0, weight=1) ### added
...
Result:
