The clone feature of the Meta Box plugin allows us to create multiple inputs from a text, textarea, select, … fields without declaring many fields in the code.

Making a field cloneable

To make a field cloneable, just add 'clone' => true to field’s parameter. After doing that, you’ll see a new + (Add Clone) button below field input:

Clicking on that button will duplicate field input:

You can notice that there are new buttons - (Remove Clone) which allow you to remove clones.
