# HasInputFieldElement

> Convenience mixin grouping common capabilities of Vaadin input fields

## Overview

`HasInputFieldElement` is a convenience mixin interface that groups common capabilities of Vaadin input field components. It combines several specialized interfaces to provide a unified set of features for components that support labels, values, helper text, and styling.

This interface does not define any methods of its own but serves as a composition of other mixin interfaces, providing a convenient way to declare that an element supports all standard input field capabilities.

**Interface Location:** `org.vaadin.addons.dramafinder.element.shared.HasInputFieldElement`

## Composed Interfaces

`HasInputFieldElement` extends the following interfaces:

* `HasHelperElement` - Helper text support via helper slot
* `HasValueElement` - Value handling for input fields
* `HasStyleElement` - CSS class styling support
* `HasLabelElement` - Visible label support

## Methods

Since this interface is a pure composition mixin, it inherits all methods from its parent interfaces. See the individual interface documentation for available methods:

* [HasHelperElement](/api/shared/has-helper) - Methods for helper text
* [HasValueElement](/api/shared/has-value) - Methods for value handling
* [HasStyleElement](/api/shared/has-style) - Methods for CSS styling
* [HasLabelElement](/api/shared/has-label) - Methods for label handling

## Implementing Classes

The following element classes implement `HasInputFieldElement`:

* `TextFieldElement` (and its subclasses: `TextAreaElement`, `PasswordFieldElement`, `EmailFieldElement`)
* `AbstractNumberFieldElement` (and its subclasses: `NumberFieldElement`, `IntegerFieldElement`, `BigDecimalFieldElement`)
* `DatePickerElement`
* `DateTimePickerElement`
* `TimePickerElement`
* `ComboBoxElement`
* `MultiSelectComboBoxElement`
* `SelectElement`

## Usage Example

```java theme={null}
import org.vaadin.addons.dramafinder.element.TextFieldElement;
import com.microsoft.playwright.Page;

public class InputFieldTest {
    void testInputField(Page page) {
        // Get a text field by its label
        TextFieldElement field = TextFieldElement.getByLabel(page, "Email");
        
        // Methods from HasLabelElement
        field.assertLabel("Email");
        
        // Methods from HasValueElement
        field.setValue("user@example.com");
        field.assertValue("user@example.com");
        
        // Methods from HasHelperElement
        field.assertHelperHasText("Enter your email address");
        
        // Methods from HasStyleElement
        field.assertCssClass("custom-field");
    }
}
```

## Design Purpose

This mixin interface follows the **Composition Pattern** to avoid code duplication across input field implementations. Instead of each input field class implementing the same set of interfaces repeatedly, they can simply implement `HasInputFieldElement` to gain all standard input field capabilities.

* [HasPlaceholderElement](/api/shared/has-placeholder) - Commonly combined with input fields
* [HasClearButtonElement](/api/shared/has-clear-button) - Often used with text inputs
* [FocusableElement](/api/shared/focusable) - Focus management for interactive fields
