Hello, I am using you library and is working great now (Thanks) but I have to make a few changes to make it work.

1. First one was that the menu was render side wise not vertical. Maybe this is only with my display library. To fix it I swap the variables in render().

    def _render_cursor(self):
        for l in range(0, self.lines):
            self.lcd.move_to(0, l)

and

  def _render_options(self):
        # Render the options:
        for l, option in enumerate(self.viewport):
            self.lcd.move_to(1, l)  # Move to the line

2)When I have more than 8 options the view chunk retrun was off. With this code is working for me (also no need of import math anymore):

    def _current_chunk(self):
        return int((self.focus -1) / (self.lines ))  # current chunk

3. and finally I added the variable self.current with the menu object been render so I can control the sub menus more easily:

    def __init__(self, title, render_title=False):
        self.current = self

    def parent(self):
        if self.parent_menu:
            self.active = False
            self.parent_menu.current = self.parent_menu
            return self.parent_menu.start(self.lcd)

    def _choose_menu(self, submenu):
        self.active = False
        self.current = submenu

thanks for sharing the library. Regards.

Good afternoon. I'm trying to implement a menu on the 2004 display. The code will be below. The problem is that when activated, the menu does not show the entire list of items on the screen, but only the last one. And also, instead of the cursor on the screen, the letters "SA". What could be the problem?
If the menu works fine, the next question is: how to fasten the execution of the interrupt function to it.
`called_back_main = False
called_back_sub = False

def action_callback_main():
global called_back_main
print ("Действие главного меню")
called_back_main = True
def action_callback_sub():
global called_back_sub
print ("Действие подменю")
called_back_sub = True

submenu = Menu("Submenu")
submenu_action_1 = MenuAction("Submenu Action", callback=action_callback_sub)
submenu_action_2 = MenuAction("Submenu Action 1", callback=action_callback_sub)
submenu.add_option(submenu_action_1)
submenu.add_option(submenu_action_2)

menu = Menu("Main menu")
menu_action_1 = MenuAction("Action_1", callback=action_callback_main)
menu_action_2 = MenuAction(" Action_2", callback=action_callback_main)
menu.add_option(submenu)
menu.add_option(menu_action_1)
menu.add_option(menu_action_2)
menu.add_option(MenuNoop(" Главное меню"))

current_menu = menu.start(lcd)`
