# getAvailableProductOptions()

## Signature

```php
public function getAvailableProductOptions(): array
```

## Description

Basically this method returns a key-value array where the key is the technical name of the option and the value is an instance of `ProductOptionField()`.

## Field types

hostware options support text, number, dropdown and boolean options. In the next section you learn how to configure them.

## Example

Every field after the display name is optional. 

{% code fullWidth="false" %}

```php
return [
	// Use the technical name, which can later be used to retrieve the value, as key
	"virtualization" => new ProductOptionField(
		ProductOptionFieldEnum::DROPDOWN, // The type of the field
		"Virtualization",                 // The displayed name in the administration (should be english)
		null,                             // The optionally displayed description in the administration (should be english)
		"qemu",                           // The default value
		[                                 // The dropdown key-value array, where the value is the label in the administration
			'qemu' => 'KVM',
			'lxc' => 'LXC',
		],
		true                               // Set to true if this option can only be configured via product option. Use-case are e.g. fields for the products hostname.
