Anatomy

You can combine the following parameters:

• leading_icon

• text

• trailing_icon

• trailing_text

…to create the necessary types of menu items:

menu_items = [
    {
        "text": "Strikethrough",
        "leading_icon": "check",
        "trailing_icon": "apple-keyboard-command",
        "trailing_text": "+Shift+X",
    }
]

menu_items = [
    {
        "text": "Strikethrough",
        "trailing_icon": "apple-keyboard-command",
        "trailing_text": "+Shift+X",
    }
]

menu_items = [
    {
        "text": "Strikethrough",
        "trailing_icon": "apple-keyboard-command",
    }
]

menu_items = [
    {
        "text": "Strikethrough",
        "trailing_text": "Shift+X",
    }
]

menu_items = [
    {
        "text": "Strikethrough",
        "leading_icon": "check",
        "trailing_icon": "apple-keyboard-command",
    }
]

menu_items = [
    {
        "text": "Strikethrough",
        "leading_icon": "check",
    }
]

menu_items = [
    {
        "text": "Strikethrough",
        "leading_icon": "check",
        "trailing_text": "Shift+X",
    }
]

menu_items = [
    {
        "text": "Strikethrough",
    }
]

You can use the following parameters to customize the menu items:

• text_color

• leading_icon_color

• trailing_icon_color

• trailing_text_color

menu_items = [
    {
        "text": "Strikethrough",
        "leading_icon": "check",
        "trailing_icon": "apple-keyboard-command",
        "trailing_text": "+Shift+X",
        "leading_icon_color": "orange",
        "trailing_icon_color": "green",
        "trailing_text_color": "red",

Menu with MDTopAppBar

The MDDropdownMenu works well with the standard MDTopAppBar. Since the buttons on the Toolbar are created by the MDTopAppBar component, it is necessary to pass the button as an argument to the callback using lambda x: app.callback(x). This example uses drop down menus for both the righthand and lefthand menus.
