The body section of the menu can be used for three different purposes:

• Status
### 2.1 List Menu
The list menu allows the listing of submenus. Additionally, three buttons can be defined at the bottom.
To create a list menu, the following steps must be defined:
```cpp
menu->bodyItemEnable(menu->ListMenu);
menu->headerSetText("Title");
menu->bodyMenuAddItemToList("1st Item", "", 1);
menu->bodyMenuAddItemToList("2nd Item", "", 2);
…..
…..
menu->bodyMenuCreateItemList();
```
### 2.2 Pop-up Menu
The **Pop-up menu** is a type of menu that appears over the active menu and is used for purposes such as warnings, errors, information, and asking questions.
```cpp
menu->bodyPopUpSetHeader(CBody_PopUp::Confirmation, "POPUP Header");
menu->bodyPopUpSetButtons(CBody_PopUp::Ok_Cancel, " OKEY", " CANCEL");
menu->bodyPopUpSetText("Warning Message", 2);
menu->bodyPopUpShow();
int ret = 0;
menu->bodyPopUpGetRet(&ret);
if(ret == 0)
{
// press Okey
}
else
{
// press Cancel
}
```
### **2.3 Status Notification Menu**
This menu type is used to provide status notifications related to performed operations.
```
menu->bodyItemEnable(menu->TextLine);
menu->footerClearButtonContents();
menu->bodyTextWrite("State Message", 2 /*Line No*/);
```
### **2.4 Edit Menu**
The **Edit Menu** allows data entry using the keypad.
```cpp
menu->bodyItemEnable(menu->EditLine);
menu->bodyEditLineSetFormat(CBody_EditLine::Amount, 10);
menu->headerSet("Header");
menu->bodyEditLineSetTitle("EditBox Message");
```
