How to populate a set of fields multiple time in the page ?

Question

Hi All,
JDev Ver : 11.1.1.5
I have a requirement as follows,
My page contains 1. Add Button
2. Five fields.(one input text and four select one choice)
The fields are like one input text and remaining select one choice. And also these fields contains validations.
Actions
On click of add button , I have to show the fields , similarly I have to add one more set of fields in the page below the first set when I click the add button, Like this I will add as many as I need.
How to achieve this requirement,
1. Do I need to generate the view objects dynamically from managed bean ?
2. Do I need to create a custom component ?
For Time being , I have added 3 set of fields pages and showing one by one. I want to do this dynamically.
Please let me know the suggestion for this Requirement.
Thanks,

Hi,
to do this:
1. reate a managed bean that exposes a HashMap property. The HashMap is of type e.g. Map<Person>
2. To create a new set of fields, add a new entry to the HashMap and refresh the af:form. The af:form contains and af:forEach that you use
to iterate as often as you have entries in the HashMap. Each text field you bind to #{bean.HashMapProperty['key'].attribute}, for example
#{bean.HashMapProperty['key'].FirstName}
#{bean.HashMapProperty['key'].LastName}
#{bean.HashMapProperty['key'].EmployeeId}
3. When the user updates a field, the HashMap is updated based on the "key"
4. The managed bean should be in viewScope and referenced from the field's value property
