1# @ohos.inputMethodList (Input Method List) 2<!--Kit: IME Kit--> 3<!--Subsystem: MiscServices--> 4<!--Owner: @illybyy--> 5<!--Designer: @andeszhang--> 6<!--Tester: @murphy1984--> 7<!--Adviser: @zhang_yixin13--> 8 9The **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. 10 11> **NOTE** 12> 13> 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. 14 15## Modules to Import 16 17```ts 18import { InputMethodListDialog } from '@kit.IMEKit'; 19``` 20 21## Child Components 22 23Not supported 24 25## Attributes 26The [universal attributes](../apis-arkui/arkui-ts/ts-component-general-attributes.md) are not supported. 27 28## InputMethodListDialog 29 30InputMethodListDialog({controller: CustomDialogController, patternOptions?: PatternOptions}) 31 32Implements a dialog box showing the input method list. 33 34**Decorator type**: @CustomDialog 35 36**System capability**: SystemCapability.MiscServices.InputMethodFramework 37 38**Parameters** 39 40| Name| Type| Mandatory| Decorator| Description| 41| -------- | -------- | -------- | -------- | -------- | 42| controller | [CustomDialogController](../apis-arkui/arkui-ts/ts-methods-custom-dialog-box.md#customdialogcontroller) | Yes| - | Controller for the dialog box showing the input method list.| 43| patternOptions | [PatternOptions](#patternoptions) | No| - | Input method pattern options (for the default input method only).| 44 45## PatternOptions 46 47**System capability**: SystemCapability.MiscServices.InputMethodFramework 48 49| Name| Type| Read-Only| Optional| Description| 50| -------- | -------- | -------- | -------- | -------- | 51| defaultSelected | number | No| Yes| Optional.
