control p5: How to access "name" or "text" property in ScrollableList?

Hi, I have a simple question about ScrollableLists in controlP5.

I want to acces the "name" or "text" behind the items in a ScrollableLists.

How do I access them, and for instance set a string (in code below named "selected") equal to the value of the item on the list that is selected?

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

ControlP5 cp5;

String selected = "";

void setup() {
  size(400, 400);
  cp5 = new ControlP5(this);
  List l = Arrays.asList("a", "b", "c", "d", "e", "f", "g", "h");
  cp5.addScrollableList("dropdown")
     .setPosition(100, 100)
     .setSize(200, 100)
     .setBarHeight(20)
     .setItemHeight(20)
     .addItems(l)
     ;
}

void draw() {
  background(120);
  text("You have selected: " + selected, 100, 300);
}
