+# [Add Permission Dialog Component](../../../lib/content-services/permission-manager/components/add-permission/add-permission-dialog.component.ts "Defined in add-permission-dialog.component.ts")
+
+Displays a dialog to search for people or groups to add to the current node permissions.
+
+![Add Permission Component](../../docassets/images/add-permission-component.png)
+
+## Basic Usage
+
+```ts
+import { NodePermissionDialogService } from '@alfresco/adf-content-services';
+
+    constructor(private nodePermissionDialogService: nodePermissionDialogService) {
+    }
+
+    this.nodePermissionDialogService.openAddPermissionDialog(this.nodeId).subscribe((selectedNodes) => {
+        //action for selected nodes
+    },
+    (error) => {
+        this.showErrorMessage(error);
+    });
+```
+
+## Details
+
+This component extends the [Add permission panel component](add-permission-panel.component.md)
+to apply the chosen selection of permissions when they are accepted.
+You can open the dialog with the `openAddPermissionDialog` method from the
+[Node Permission Dialog Service](../services/node-permission-dialog.service.md).
+This returns an [`Observable`](http://reactivex.io/documentation/observable.html)
+that you can subscribe to so you can get the details of the node after the update.
+Use the `updateNodePermissionByDialog` nethod from the service to update node permissions, as shown in
+the following example:
+
+```ts
+import { NodePermissionDialogService } from '@alfresco/adf-content-services';
+
+    constructor(private nodePermissionDialogService: nodePermissionDialogService) {
+    }
+
+    this.nodePermissionDialogService.updateNodePermissionByDialog(this.nodeId).subscribe((node) => {
+        //updated node
+    },
+    (error) => {
+        this.showErrorMessage(error);
+    });
+```
