Add blank select value to dropdown list

ginacargile

I see there was a request for this functionality 11/15. If it hasn't been added, is there a workaround?

I've added this and the dropdown still just selects the first option in the list.
.SetFormatter(Format.IfEmpty(null))

Thanks!

You can do it on the client-side using the placeholder option of the -field select field type which was introduced in 1.5.4.

Are you saying like this? I tried it this way and it doesn't change anything. (no error either)

{
label: "Location:",
name: "LocationID",
type: "select",
options: {
placeholder: "--Select--"
}

Nevermind! I got it:

{
label: "Location:",
name: "LocationID",
type: "select",
placeholderDisabled: false,
placeholder: ""
}
