parent_child_checkbox

Parent Child Checkbox is a type of checkbox where we can establish hierarchy in Checkboxes.

You can create a Parent Checkbox which has multiple checkboxes as their children! The value of parent checkbox depends on the value of children checkboxes and vice-versa.
If we clicked on Parent Checkbox, all children checkboxes will be selected too.
