I want the select-option to open when I click on the radio button

There are 2 radio buttons on a selection screen. Then select the option that appears, I will enter the information and show it on ALV. I want different select options to be opened for the two buttons.

Definitions :

PARAMETERS : p_rad1 RADIOBUTTON GROUP rad1 DEFAULT 'X' USER-COMMAND seher,
             p_rad2 RADIOBUTTON GROUP rad1.

SELECT-OPTIONS: so_lifnr FOR lfa1-lifnr NO INTERVALS NO-EXTENSION,
                so_kunnr FOR kna1-kunnr NO INTERVALS NO-EXTENSION,
                so_bkr_l FOR lfb1-bukrs NO INTERVALS NO-EXTENSION,
                so_bkr_k FOR knb1-bukrs NO INTERVALS NO-EXTENSION.

I want SO_LIFNR and SO_BKR_L for p_rad1, SO_KUNNR and SO_KUNNR for p_rad2. I wrote this way:

  LOOP AT SCREEN.
    IF screen-name CS 'SO_LIFNR'.
       IF NOT p_rad1 IS INITIAL.
         screen-active = 1.
       ELSE.
         screen-active = 0.
       ENDIF.
       MODIFY SCREEN.
    ELSEIF screen-name CS 'SO_BKR_L'.
       IF NOT p_rad1 IS INITIAL.
         screen-active = 1.
       ELSE.
         screen-active = 0.
       ENDIF.
       MODIFY SCREEN.
    ELSEIF screen-name CS 'SO_KUNNR'.
       IF NOT p_rad2 IS INITIAL.
         screen-active = 1.
       ELSE.
         screen-active = 0.
       ENDIF.
       MODIFY SCREEN.
    ELSEIF screen-name CS 'SO_BKR_K'.
       IF NOT p_rad2 IS INITIAL.
         screen-active = 1.
       ELSE.
         screen-active = 0.
       ENDIF.
       MODIFY SCREEN.
    ENDIF.
  ENDLOOP.

But it gives me such an output. It works correctly but this screen is wrong :

I want it to look separate like this example. Separate images for two radio buttons.

For p_rad1 :

For p_rad2:

How can I do that?
