In NVL mode, how to make the newly appeared text to the left of the previous text instead of the bottom?

[yhsxsx]

I use vertical to make the text vertical, but I want the next text to be arranged in the way shown in Figure 1, not now (Figure 2).

Code: Select all

screen nvl(dialogue, items=None):
   
    window:
        style "nvl_window"
        if nvl_bg ==1:
            background None
        else:
            background  Frame("gui/01_light.png")
        has vbox:
            style "nvl_vbox"

        
        for d in dialogue:
            window:
                id d.window_id

                has hbox:
                    spacing 30

                if d.who is not None:
                    text d.who id d.who_id

                text d.what:
                 id d.what_id
                 adjust_spacing True
                 line_spacing 5
                 outlines [(out,"#FFFFFF",0,0)]
        
        if items:

            vbox:
                id "menu"

                for i in items:

                    if action:

                        button:
                            style "nvl_menu_choice_button"
                            action i.action

                            text i.caption style "nvl_menu_choice"

                    else:

                        text i.caption style "nvl_dialogue"
