# @ohos.inputMethodList (Input Method List)

The **inputMethodList** module is oriented to system applications and input method applications. It provides APIs for implementing an input method list. This list displays the default input method subtypes and third-party input methods. Users can use this list to switch from the default input method to another input method.

> **NOTE**
>
> The initial APIs of this module are supported since API version 11. Updates will be marked with a superscript to indicate their earliest API version.
