good point, currently you can only hide the whole scrollList with hide(), show/hide the bar (showBar()/hideBar) and/or show/hide the scrollBar (showScrollbar()/hideScrollbar()). you can't yet show the top bar only - there is no option to expand and hide the scrollList items yet, but should be useful. i put it on the todo list.

a work around would be to put the scrollList into a ControlGroup at position 0,0. hide ScrollList's top bar and i think you get what you are looking for,.
Code:

  ScrollList myScrollList = controlP5.addScrollList("myList",0,0,120,280);
  myScrollList.hideBar();
  for(int i=0;i<20;i++) {
    controlP5.Button b = myScrollList.addItem("a"+i,i);
  }  
  
  ControlGroup l = controlP5.addGroup("myGroup",40,60,120);
  myScrollList.moveTo(l);
  l.close();

best,
andreas

Thanks for your hints! Actually it works also with just using the .close(). I really dont know why i did not manage to do this before.
I just puzzle about how to avoid graphical overlaps when using more (closed)scrollLists closely located to each other.
import controlP5.*;
ControlP5 controlP5;


void setup() {
size(400,400);
controlP5 = new ControlP5(this);
 
 ScrollList ScrollListOne = controlP5.addScrollList("myList_1",30,20,120,200);
 for(int i=0;i<20;i++) {
   controlP5.Button b = ScrollListOne.addItem("a"+i,i);
  }  
 ScrollListOne.close();
 
 ScrollList ScrollListTwo = controlP5.addScrollList("myList_2",30,100,120,280);
 for(int i=0;i<20;i++) {
   controlP5.Button b = ScrollListTwo.addItem("b"+i,i);
  }  
 ScrollListTwo.close();
 
}
void draw() {
 background(255);
 
}

P.S.:Thanks for your great library
