#  First off we import all the things needed for this
#  example
from clitui import Menu, getchar, fg_by, bg_by, safe_run, is_pressed

#  There many ways of setting colors in clitui but here is one where
#  We made a global variable to use throughout code
FG_CYAN = fg_by(0, 160, 160)

# We first create instances of any kind of menu or submenui
# with Menu class.  Menu takes a x and y and an option argument
# if no x, y is given submenu's default to parant menu's x, y.
main_menu = Menu("Main Menu", x=10, y=10)
options_menu = Menu("Options Menu")
key_controls = Menu("Key Controler")

# to set color for any menu or submenu just call background_color method.
# it takes a wide array of valid options.
# string of "black" or "cycan"
# a tuple (0, 160, 160) or just put bg_by function directly in there
main_menu.background_color((50, 0, 0))

# here we add items to are menu
# you can stack method calls on here as well
# you need a Name and a id for all menu items.
main_menu.add("New Game", 0).font_color_for(0, (0, 255, 0))
main_menu.add("Load", 1).font_color_for(1, FG_CYAN)
main_menu.add("Save", 2).font_color_for(2, "Cyan")

# if the menu item has a submenu then give it a Menu instances
# in submenu method
main_menu.add("Options", 3).submenu(3, options_menu)
main_menu.add("Exit", 4).add_action(4, exit)

# here we are adding submenu items

key_controls.add("Key0", 0)
key_controls.add("Key1", 1)

# finally we call the create method to genorate all the need
# items for drawing.

        # method

#  module in clitui but it is advised to use the safe_run function so you dont get
#  your terminal out of sync
