array( 
'label'   => 'Alignement', 
'attr'    => 'float', 
'type'    => 'select', 
'placeholder' => 'right' // default value - for text and textarea fields, perhaps other types 
'value'   => 'right', // default value 
'options' => array( // List of options  value => label 
'left'  => 'Left', 
'right' => 'Right', 
'none'  => 'None' 
), 
),

'text' => array(),
'textarea' => array( 'template' => 'shortcode-ui-field-textarea',
'url' => array( 'template' => 'shortcode-ui-field-url',
'select' => array( 'template' => 'shortcode-ui-field-select',
'checkbox' => array( 'template' => 'shortcode-ui-field-checkbox',
