implement "combobox with like search" inside class Tk-CodePudding

I have the following code:

I need to implement the code inside the class https://stackoverflow.com/a/65821591/12759374 Exactly this function:


def check_input(event):
    value = event.widget.get()

    if value == '':
        combo_box['values'] = lst
    else:
        data = []
        for item in lst:
            if value.lower() in item.lower():
                data.append(item)

        combo_box['values'] = data

and this execution:


combo_box.bind('<KeyRelease>', check_input)

How to union these two solutions? So, I have 7 RadioButtons, dropdown lists based on selected RadioButtons, but I have 1 list where more than 300 elements, so I want to realize to search function inside given dropdown list.

I did it, thank you!
