Reference field not showing up as Dropdown - Why?

[G24]

Guys, what am I doing wrong here?

On the incident form, I defined a new field, which is a REFERENCE to another field, as follows:

But it's not showing up as a "Dropdown".  It's showing up as a Lookup Dialog.   There is a magnifying glass icon, and clicking on that causes a popup dialog to appear.  It's a lot more "clunky" than the simple dropdown.

I'm sure this is an ID 10 T error, so apologies in advance.  Thanks for helping.

Hi @G24,

Follow the below steps. It will help you to she reference field as drop-down.

1) Select the Choice List Specification section options as

• Dropdown with --None--
• Dropdown without --None--

2) Add the field attributes with comma separated.

ref_auto_completer=AJAXReferenceChoice

Thanks, @Ravi Chandra_K and @Sagar Pagar 

It ended up being THIS property that I needed to change: glide.xmlhttp.max_choices 

But I'm still very unclear on the difference between that and glide.ui.max_ref_dropdown.  Do you guys understand the difference?  As described here ?

[Ravi Chandra_K]

Hello @G24 

glide.xmlhttp.max_choices - control the number of recent selection the system displays.

glide.ui.max_ref_dropdown - if the no.of values in table are more than what defined here (default 25), it will populate as reference Icon.
