The rich menu is a customizable menu that is displayed on the chat screen to help users interact with your LINE official account. You can customize the menu items to correspond to various actions.
Rich menu structure
The rich menu is made up of a rich menu image and a chat bar.
- Rich menu image: Image that has one or more defined tappable areas to which you specify certain actions such as returning a postback event or opening a URL.
- Chat bar: The user opens and closes the rich menu from here. You can customize the text of this bar.
Types and display priority of rich menus
There are three types of rich menus as below, depending on the setting method and the target users.
|Type||Setting method||Target users||Display priority|
|Per-user rich menu set with the Messaging API||Messaging API||Individual user||1|
|Default rich menu set with the Messaging API||Messaging API||All users who have added your LINE official account as a friend||2|
|Default rich menu set with LINE Official Account Manager||LINE Official Account Manager||All users who have added your LINE official account as a friend||3|
You can assign these three types of rich menus to one user at the same time. In that case, the priority order in the table above determines the rich menu to be displayed on the chat screen.
When setting change takes effect
When you change the setting of a rich menu, it becomes effective at different timings depending on the type of the rich menu as below.
|Type||When change takes effect|
|Per-user rich menu set with the Messaging API||Immediately. However, if you delete the rich menu without unlinking it from the user, the deletion takes effect when the user re-opens the chat screen.|
|Default rich menu set with the Messaging API||When the user re-opens the chat screen. It may take up to one minute until the change takes effect.|
|Default rich menu set with LINE Official Account Manager||When the user re-opens the chat screen|
