How to populate multi select pick list from parent to child and child multi select pick list should be selectable while creating child records

How to populate multi select pick list from parent to child and child multi select pick list should be selectable while creating child records
Eg : Parent A has Multi Select picklist field as "picklist11" and having "x,y,z" as values, suppose if i try to create Child A record, i want same picklist should be available at child where i can select values as "x,y,z OR x,z OR y,z OR y OR x " etc 


Can someone suggest how to achieve this declaratively

The only way you can able do it using the visualforce ror  lightning developer by override the child new record creation button 

The problem with the trigger or process builder is you can populate the value but which is not selectable on the new button click 


So you need to create VF page and override the new button
