    <MenuItems>
        <MenuItem Text="File">
            <MenuItems>
                <MenuItem Text="Open"></MenuItem>
                <MenuItem Text="Save"></MenuItem>
                <MenuItem Text="Exit"></MenuItem>
            </MenuItems>
        </MenuItem>
        <MenuItem Text="Edit">
            <MenuItems>
                <MenuItem Text="Cut"></MenuItem>
                <MenuItem Text="Copy"></MenuItem>

Common Patterns

Pattern 1: Simple Hardcoded Menu

Use direct MenuItem components for small, static menus. This is the simplest approach and requires no data binding setup.

Pattern 2: Data-Bound Menu from List

Use MenuFieldSettings to bind a List to your menu. Perfect for dynamic menus sourced from databases or APIs.

Pattern 3: Self-Referential Data

Map ParentId relationships in flat data to create hierarchical menus. Ideal for category/subcategory structures.

Pattern 4: Event-Driven Menus

Use MenuEvents to respond to user actions (Created, ItemSelected, OnOpen, OnClose). Essential for tracking user navigation.

Pattern 5: Styled and Animated Menus

Combine IconCss, MenuAnimationSettings, and Orientation for visually appealing, professional menus.
