How to Populate Parent object picklist selected values on child object picklist?

Hi All,

I have Parent object with multiselect picklist(CC,ACH,Cash,Check).
I have Child Object picklist with same values. Here Student Edit and Detail pages are Visualforce pages.
Requirement is Whatever the picklist values selected in Parent object those values only be populated on Child object and remainig values should not be visible. I tried with following Code but remaining values are visible.

String parenturl = apexPages.currentPage().getParameters().get('retURL');
                parenturl .trim();
                if(parenturl .contains('/'))
                    parenturl = parent .subString(1);
                Id locIdId = Id.valueOf(parent url);

child.multiselect__c = child.Parent__r.picklist__c;

This feature idea is also under consideration as can be seen on our idea exchane:
