Accessing selected list elements from ControlP5 dropdown list

Hi guys,

What should I do to be able to print the relevant item? eg: I want the console to print out just the word 'ADD' or 'SUBTRACT' and so on. I want to later use this as part of a String Variable to pass into the default blendMode() function. That way I will be able to allow for user input/choice of blendMode. That way it would read as blendMode(ADD) or blendMode(SUBTRACT).

I tried getName(), etc but was not able to access it. Right now it prints:

1 {text=SUBTRACT, color=bg (0,45,90), fg (0,116,217), active (0,170,255), captionlabel (255,255,255), valuelabel (255,255,255), name=SUBTRACT, state=false, value=1, view=controlP5.ScrollableList$1@66a35419}

import controlP5.*;
import java.util.*;


ControlP5 cp5;

void setup() {
  size(400, 400);
  cp5 = new ControlP5(this);
  List l = Arrays.asList("ADD", "SUBTRACT", "DARKEST ", "LIGHTEST ", "DIFFERENCE", "EXCLUSION",
  "MULTIPLY", "SCREEN", "OVERLAY", "HARD_LIGHT", "SOFT_LIGHT", "DODGE", "BURN");
  /* add a ScrollableList, by default it behaves like a DropdownList */
  cp5.addScrollableList("dropdown")
    .setPosition(100, 100)
      .setSize(200, 100)
        .setBarHeight(20)
          .setItemHeight(20)
            .addItems(l)
              .setType(ScrollableList.DROPDOWN) // currently supported DROPDOWN and LIST
                ;
}

void draw() {
  background(240);
}

void dropdown(int n) {
  /* request the selected item based on index n */
  println(n, cp5.get(ScrollableList.class, "dropdown").getItem(n));

  /* here an item is stored as a Map  with the following key-value pairs:
   * name, the given name of the item
   * text, the given text of the item by default the same as name
   * value, the given value of the item, can be changed by using .getItem(n).put("value", "abc"); a value here is of type Object therefore can be anything
   * color, the given color of the item, how to change, see below
   * view, a customizable view, is of type CDrawable
