"Add More" input to dropdown list

Question

Hello,
I was having some difficulty trying to customize this dropdown list to a format very similar to one of the dropdown options on ebay.
The cell is blank and has a drop down. Once you click the drop down, you will find the following
relaxed
straight leg
other
When you click "other," the field box now contains the  text that reads " Enter a Specific Value." and you are able to add in whatever text you want in the field
That would be great if there was a way in LiveCycle to do something close to or exactly like this.
thanks

Answer 1

1) allow custom text entry
2) add exit event
// form1.page1.dd::exit - (JavaScript, client)
if (this.rawValue == "Other") {
  this.rawValue = "Enter a specific value";
3) add entry event
// form1.page1.dd::enter - (JavaScript, client)
if (this.rawValue == "Enter a specific value") {
  this.rawValue = "";
