# User

The **User** component adds a drop-down list that allows users to select existing users. You can configure the component to allow either a single selection or multiple selections. To narrow down the choices, you can provide a **Proposed values** list, which restricts the drop-down to only those specific users.

For single selection components, the class of the stored value is String, representing the ID of the selected item.

For multiple selection components, the class of the stored value is ArrayList, representing a comma-separated list of the IDs of the selected items.

| ID            | The identifier of the component, primarily used for client-side interactions and identification in the HTML structure of the form. When you add a component, an ID is automatically generated to ensure it is unique in the form.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  |

## Datasource properties

Datasource properties are common to the components that accept a list of items or options.

| Custom validations | <p>A list of additional validations for the component. Each custom validation consists of two parts:</p><ul><li><strong>Expression</strong>: A rule that must evaluate to <code>true</code> for the form to be submitted.</li><li><strong>Error message</strong>: The message that shows if the expression evaluates to <code>false</code>.</li></ul><p>For example, you can create a validation with the expression <code>{{experience>2}}</code>. This expression evaluates to <code>true</code> only if the value of the <code>experience</code> variable is greater than 2.</p> |

| Ignored     | Whether the component is be hidden in the form and any value it might hold is not included in the submission data.                                                                                                                                                                    |
| Visible     | Whether the component is shown or hidden on the form. You can controlled this unconditionally or through an expression. For example, you can set an expression that hides or shows the component based on a user selection in another component. This property is enabled by default. |
| Enabled     | Whether the component is interactive or read-only on the form. When disabled, users cannot change the component value. This property is enabled by default.                                                                                                                           |
