Generics usage with combined enum & interface class

Question

I would like to use an enum to store constants for a drop down list, and be able to reuse the structure in a generics method. What I have done is created a interface with basic functionality, and then created an Enum class that implements my interface. Now that I have a single class, I want to pass the resulting class to a static helper function that will have access to the interface functions, and still have the ability to use the benefits of the enum (foreach loops & access to enum constants).
Is there a way to do this with Generics? I know that this is not right, but maybe it will give an idea of what I am trying to do: <? extends <Enum extends Menu_Interface>>.
public interface Selection_List {
     public String getName();
     public void setName( String name );
     public String getValue();
     public void setValue( String value );
     public String getGroup();
     public void setGroup( String group );
     boolean isSelected();
public enum Tool_Types implements Selection_List
     SAMPLE_ONE( "name1", "value1" ),
     SAMPLE_TWO( "name2", "value2" );
     // ... implementation of interface functions
public class FormGenerator
     public static <T extends <Enum extends Selection_List>>
          String doCreateDropDown( T selectionList )
          //  ... implementation of function
};

You surely can. The following is an example on implementing Runnable:
public class EnumWithInterface {
    enum Days implements Runnable {
     MON, TUE, WED, THU, FRI, SAT, SUN;
     @Override
     public void run() {
         System.out.println("Running " + this);
    static <E extends Enum<E> & Runnable> void runAll(Class<E> runnableEnum) {
     for (E e : runnableEnum.getEnumConstants()) {
         e.run();
    public static void main(String[] args) {
     runAll(Days.class);
}
