Auto populate a drop down menu from text field entries?

I have been searching the forums for hours but cannot find a solution for this, which seems like it would be more simple than much of the questions I have been looking at. I do not have much experience with running scripts in Acrobat, but I am willing to learn. I have seen many forum answers referring to "LiveCycle", but I don't think I have that. I am running Adobe Acrobat CC and all is up to date.

I want to create a fillable PDF where there is a dropdown menu that populates its options with the text from text fields earlier in the document that the user fills out. Is this possible?

I would do it using a (hidden) text field with the following calculation script:

var textFields = ["Text1", "Text2", "Text3", "Text4", "Text5"];
if (event.source!=null && textFields.indexOf(event.source.name)!=-1) {
    var items = [];
    for (var i in textFields) {
        items.push(this.getField(textFields).valueAsString;
    }
    this.getField("Dropdown1").setItems(items);
}

The field names in the array and in line # need to be adjusted, of course.

So you want to copy the value selected in the drop-down to a text field? If so, use this code as the custom calculation script of the text field:

event.value = this.getField("Dropdown 5").valueAsString;

Use the actual field name in your file, of course.

Thank you for your interest try67 Here is the code:

var textFields = ["Original story", "Me story", "Opposite story", "Desired story"];    if (event.source!=null && textFields.indexOf(event.source.name)!=-1) {      var items = [];      for (var i in textFields) {          items.push(this.getField(textFields).valueAsString;      }      this.getField("Dropdown1").setItems(items);  }

As the error message says, you're missing a closing parenthesis, namely in this line:

items.push(this.getField(textFields).valueAsString;

It should be:

items.push(this.getField(textFields).valueAsString);

Hello,

Thank you for your help. I am newbie to this coding...
I have the same desire ; creating a dropdown list auto populated from text fields. I have done these steps:

1- I created an invisible text field

2- "Copy and paste" the above script under properties/calculation of the invisible text field

3- changes "text1", " text2" .... to their appropriate names.

then I got this error

So, my question is: are the steps correct/enough to make it done? How to fix the error

Thank you for your care!

Yes, but it's tricky. You need to define when the drop-down list should be updated. Is it each time one of the text fields is changed? What if the user already made a selection in it? etc.

Ideally it would update each time the text fields are changed.

For specifics, it is an application where I am asking users to describe a project and later create a timeline for it. So, I have users breaking their projects into up to five over arching "work elements", and then later breaking out a timeline to describe the smaller steps for the projects. Because steps from each work element will likely happen concurrently, I was hoping to allow users to enter a step in the timeline and then select the work element it was related to. That way, the timeline can be chronological and show overlapping work between "work elements".
