| Item | Description |
| --- | --- |
| Class | Click this radio-button to add a component from a class library. You can enter a fully qualified class name in the text field or click the ellipsis button and select a class from the libraries, or project. Note that code completion is available in the text field.  |
| Form | Add an existing GUI form. You can enter a fully qualified form name in the text field, or click the ellipsis button and select a form from the libraries, or project.  |
| Icon | Specify the fully qualified name of the icon file, or click the ellipsis button and select an icon file from the libraries, or project.  |
| Group | Select the target group where the new component will be added.   > **Tip:** > This field is available for the Add Component dialog only.    |
|  Horizontal / Vertical Size Policy  | The sizing policies define the behavior of the component when its parent container is being resized.  |
| Can shrink | If this option is checked, the size of the component can be reduced when the container is resized.  |
| Can grow | If this option is checked, the size of the component can increase when the container is resized.  |
| Want grow | If this option is checked, the size of the component can increase when the container is resized. This option has a higher priority when competing with the cells of the other components.  |
| Is container |  If this option is checked, the component can accommodate nested components and acquire some properties that pertain to the containers.  |
|  Create binding automatically  | If this option is checked, the field for the component is automatically added to the bound class.  |
| Can have attached label |  If this option is checked, the component of this type appears in the `labelFor` field of a `JLabel` component in the [property inspector](inspector.html). It is important to note that the Can have attached label option affects all components of this type on a GUI form. For example, if you check this option for `JButton` and `JCheckBox` Palette components, all instances of these components (already existing and newly added) appear in the `labelFor` field:   ![The labelFor field of a JLabel component](https://resources.jetbrains.com.cn/help/img/idea/2026.2/labelFor.png)  |
