## Details

### Selection Mode

You can specify either single selection or multiple selection (single
is the default):

#### Single selection

```html
<adf-cloud-group></adf-cloud-group>
```

![adf-cloud-group](../../docassets/images/group-cloud.component-single.png)

#### Multiple selection

```html
<adf-cloud-group
    [mode]="'multiple'">
</adf-cloud-group>
```

![adf-cloud-group](../../docassets/images/group-cloud.component-multiple-mode.png)

### Pre-selection

Usage example:

```ts
import { ObjectDataTableAdapter }  from '@alfresco/adf-core';

@Component({...})
export class MyComponent {
    groups: any;

    constructor() {
        this.groups =
            [
                {id: 1, name: 'Group 1'},
                {id: 2, name: 'Group 2'}
            ];
    }
}
```

```html
<adf-cloud-group
    [mode]="'multiple'"
    [preSelectGroups]="groups">
</adf-cloud-group>
```

### Read-only

You can use `readonly` property to set the component in `readonly` mode. Readonly mode will disable any interaction with the component.

```html
<adf-cloud-group
    [appName]="'simple-app'"
    [mode]="'multiple'"
    [preSelectGroups]="groups"
    [readOnly]="true">
</adf-cloud-group>
```

If you want to manage each group seperately you can set their readonly property at your preference.
You need to have component's readonly property set to false. Component's readonly mode overwrites groups level.

You can use `readonly` property to make preselected groups read-only in `multiple` mode.

Usage example:

```ts
import { ObjectDataTableAdapter }  from '@alfresco/adf-core';

@Component({...})
export class MyComponent {
    groups: any;

    constructor() {
        this.groups =
            [
                {id: 1, name: 'Group 1', readonly: true},
                {id: 2, name: 'Group 2', readonly: false}
            ];
    }
}
```

```html
<adf-cloud-group
    [mode]="'multiple'"
    [preSelectGroups]="groups">
</adf-cloud-group>
```

from above `preSelectGroups`, `Group 2` is removable from the `preSelectGroups` whereas `Group 1` is readonly you can not remove them.
