I have a form that has the same dropdown list on every line (over 50 of them). If I need to change an item in the list, my only option is to edit each list on every single line. Changes happen frequently. Is there really no way to have one field/list that can be the source of my dropdown lists?
Sure you can. I would do it using a (hidden) button somewhere in the vicinity of the "master" list. Say that list is called "Dropdown1" and the others are "Dropdown2" to "Dropdown50". Add a button with this code next to the first field:
var f = this.getField("Dropdown1");
var items = [];
for (var i=0; i<f.numItems; i++) {
items.push(f.getItemAt(i));
}
for (var i=2; i<=50; i++) {
this.getField("Dropdown"+i).setItems(items);
}Update the first field's items, then click the button to update the rest of them.
Just be aware that updating the lists will clear any selections you made in any of these fields.
