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.
