This is probably a silly question, but I'm new to wordpress development so easily confused at the moment. Code:
'label' => 'Repeatable',
'desc' => 'A description for the field.',
'id' => $prefix.'repeatable',
'type' => 'repeatable'
My Q: Is
'repeatable' a standard feature of wordpress, or is it something the developer has created? (have picked this code off the internet to learn).
