I changed the entryfield and dropbownbutton colors and font, but how can I change the dropdown part?

I create the Combobox element via:

keuze = tk.StringVar()
keuzes = ['keuze1', 'keuze2', 'keuze3', 'keuze4', 'keuze5']
keuzebox = ttk.Combobox(root, values=keuzes, font=font)
keuzebox.pack(side='top', padx=2, pady=2)

And changed the colors of the entryfield en dropdown button via:

    combostyle.theme_create('combostyle', parent='alt',
                 settings = {'TCombobox':
                             {'configure':
                              {'foreground'       : colorinput['foreground'],                               
                               'selectforeground' : colorinput['background'],
                               'selectbackground' : colorinput['foreground'],
                               'fieldbackground'  : colorinput['background'],
                               'arrowcolor'       : colorinput['foreground'],
                               'background'       : colorinput['background']
                              }
                             }
                            }
                           )
                           
    combostyle.theme_use('combostyle')

I hope there is a solution.
Thanks.

Its possible since the official documentation of TCL/TK(which tkinter uses) has answered the thing you have asked for:

The ttk::combobox popdown listbox cannot be configured using ttk::style nor via the widget configure command. The listbox can be configured using the

have a look at ttk::combobox manual page - Tk Themed Widget

Thanks for your answer, but this is beyond my knowledge of Thinker. Can jou please help me with a working code example voor Python?

See below. It works…

   combobox = ttk.Combobox(parent, values=values, font=font)
    
    combostyle._newfont = tkinter.font.Font(font=font)
    combobox.option_add('*TCombobox*Listbox*Font', combostyle._newfont)
    combobox.option_add('*TCombobox*Listbox.background', colorinput['background'])
    combobox.option_add('*TCombobox*Listbox.foreground', colorinput['foreground'])
    combobox.option_add('*TCombobox*Listbox.selectBackground', colorinput['foreground'])
    combobox.option_add('*TCombobox*Listbox.selectForeground', colorinput['background'])
