# SmartUI::SmartForm Class
This is a basic usage of SmartUI's ```SmartForm``` class. This class will help you build FORMS easyly without writing too many HML codes. If you want to know more about the real HTML layout, click [here](form-elements.php)

```php
SmartUI::SmartForm($fields [, $options = array()]);
```

## $fields
The ```$fields``` is an ```array``` parameter will tell the SmartForm what fields to be added. 
```php
$fields = array(
	'fname' => array(
		'type' => 'input', // or FormField::FORM_FIELD_INPUT
		'col' => 6,
		'properties' => array(
			'placeholder' => 'First name',
			'icon' => 'fa-user',
			'icon_append' => false
		)
	),
	'lname' => array(
		'type' => 'input',
		'col' => 6,
		'properties' => array(
			'placeholder' => 'Last name',
			'icon' => 'fa-user',
			'icon_append' => false
		)
	),
	// so on ...
);
```
The ```key``` of eacy item is the Field's ```name``` attribute. It is also used when referring to a field you want to customize. Each ```item``` may contain an ```array``` or ```closure``` (must return the same array format). See below:
```php
$field = array(
	'fname' => (
		'type' => SmartForm::FORM_FIELD_INPUT, // the type of field. 
		'col' => 0, // grid column
		'properties' => array() // properties of the field type
	)
)
```
