Removing items from the drop-down list

Question

Hello guys! How do I remove the selected item from a drop-down list?Here is a small script with an example, I don't understand why it doesn't work. Grateful for the help.   var dlg = new Window("dialog"); 
var conteudo = ["Item 1","Item 2","Item 3","Item 4","Item 4","Item 4","Item 4","Item 4","Item 4"]; 
var list = dlg.add("dropdownlist", undefined, undefined, {name: "list", items: conteudo}); 
list.selection= 0;
var remove = dlg.add("button", undefined, undefined, {name: "remove"}); remove.text="Remove ítem"

remove.onClick = function () {
     for (var i = list.selection.length-1; i > -1; i--)
     list.remove (list.selection[i]);
}

dlg.show();

Here is a small script with an example, I don't understand why it doesn't work. Grateful for the help. Because instead of remove.onClick = function () {     for (var i = list.selection.length-1; i > -1; i--)     list.remove (list.selection[i]);} use remove.onClick = function () {     for (var i = list.items.length-1; i > -1; i--)     list.remove (list.items[i]);}  : )
