Menu

Basic menu with sub page

A three-item main page whose third entry opens a hidden sub page.

A display-sized lv_menu holds a main page with three lv_menu_cont items labeled Item 1, Item 2, and Item 3 (Click me!). A separate sub page created with lv_menu_page_create carries a greeting label, and lv_menu_set_load_page_event wires the third item to load that sub page when clicked. lv_menu_set_page opens the main page.

Menu with root back button

A menu whose always-visible root back button pops a message box when tapped.

lv_menu_set_mode_root_back_button turns on LV_MENU_ROOT_BACK_BUTTON_ENABLED so the back button remains on the header at the top of the navigation stack. The main page holds three items and the third opens a sub page through lv_menu_set_load_page_event. A LV_EVENT_CLICKED handler calls lv_menu_back_button_is_root and, when true, creates an lv_msgbox with title Hello, text Root back btn click., and a close button.

Customized back button header

A menu with a labeled "Back" button in the header and three titled sub pages.

lv_menu_get_main_header_back_button returns the default back button, and a child lv_label adds the text Back next to its icon. The main page lists three items, each wired with lv_menu_set_load_page_event to sub pages titled Page 1 through Page 3 created via lv_menu_page_create.

Menu with floating add button

A circular floating button appends new items and matching sub pages.

The menu starts with a single main-page item wired to a greeting sub page. A circular lv_button flagged with LV_OBJ_FLAG_FLOATING is anchored to the bottom-right corner with a plus symbol background and a large theme font. Its LV_EVENT_CLICKED handler increments a counter, creates a new sub page and a new main-page row labeled Item N, links them with lv_menu_set_load_page_event, and calls lv_obj_scroll_to_view_recursive so the fresh row stays visible.

Settings menu with sidebar mode

A full Settings screen with sidebar navigation and a switch that toggles between sidebar and stacked modes.

A root page named Settings lists Mechanics, Sound, Display, and About entries inside lv_menu_section groups, with a Menu mode row that holds a lv_switch to flip between sidebar and stacked navigation through lv_menu_set_sidebar_page or lv_menu_set_page. Sub pages build slider rows such as Velocity 0..150 at 120 and a sound switch using helper builders that pair a label with an lv_slider or lv_switch. The root back button is enabled and a LV_EVENT_CLICKED handler on the menu pops an lv_msgbox saying Root back btn click. when the root back arrow is used.
