# Folder Actions service
Implements the folder menu actions for the [Document List component](../content-services/document-list.component.md).
## Class members
### Methods
- **canExecuteAction**(obj: `any`): `boolean`<br/>
Checks if an action is available for a particular item.
- _obj:_ `any` - Item to check
- **Returns** `boolean` - True if the action is available, false otherwise
- **getHandler**(key: `string`): `ContentActionHandler`<br/>
Gets the handler function for an action.
- _key:_ `string` - Identifier for the action
- **Returns** `ContentActionHandler` - The handler function
- **setHandler**(key: `string`, handler: `ContentActionHandler`): `boolean`<br/>
Sets a new handler function for an action.
- _key:_ `string` - Identifier for the action
- _handler:_ `ContentActionHandler` - The new handler function
- **Returns** `boolean` - True if the key was a valid action identifier, false otherwise
## Details
This service implements the built-in actions that can be applied to a folder
shown in a [Document List component](document-list.component.md): **delete**,
**download**, **copy** and **move** (see the
[Content Action component](content-action.component.md) for further details and examples
of these menu items). However, you can also use the service to add extra actions or
replace the built-in ones with your own implementation.
### Registering an action
In the example below, a custom handler called `my-handler` is registered with the service.
This action will invoke the `myFolderActionHandler` function each time it is selected
from the Document List menu.
```ts
import { FolderActionsService } from '@alfresco/adf-content-services';
export class MyView {
constructor(folderActions: FolderActionsService) {
folderActions.setHandler(
'my-handler',
this.myFolderActionHandler.bind(this)
);
}
myFolderActionHandler(obj: any) {
window.alert('my custom action handler');
}
}
```
The action can then be used from the component in the usual way:
```html
<adf-document-list ...>
<content-actions>
<content-action
target="folder"
title="My action"
handler="my-handler">
</content-action>
</content-actions>
</adf-document-list>
```
You can also override a built-in handler (eg, 'download') with your own function:
```ts
export class MyView {
constructor(folderActions: FolderActionsService) {
folderActions.setHandler(
'download',
this.customDownloadBehavior.bind(this)
);
}
customDownloadBehavior(obj: any) {
window.alert('my custom download behavior');
}
}
```
You will probably want to set up all your custom actions at the application root level or
with a custom application service.
