Hi ankur,

Yes, Giving you an example condition.

Have a list of servers in the choice field. Users should be able to select only 20 servers in the list for a single catalogue request,

Hi Hemanth,

Check this:

Display a reference field as a choice list

Madrid

You can display a reference field as a choice list instead of opening a lookup window.

Before you begin

Role required: personalize_dictionary

Procedure

1. In the form, right-click the label for the reference field and select Configure Dictionary.
2. In the Choice List Specification section, select one of the following options in the Choice field.
   • Dropdown with --None--
   • Dropdown without --None--
3. Right-click the form header and click Save.
4. Under Related Links, click Advanced view.
5. In the Attributes field, add the following attribute, separated from other attributes by a comma.

   ref_auto_completer=AJAXReferenceChoice

6. Click Update.
   The form reopens, with the reference field as a choice list.

   

   Note:

   The glide.ui.max_ref_dropdown system property determines whether a reference field is displayed as a choice list or a reference icon. When the number of available choices exceeds the value of this property, a reference icon displays instead of a choice list. The default value of this property is 25. This property affects the entire instance, however you can override this property on an individual field by using the max_ref_dropdown dictionary attribute. Modifying dictionary attributes requires the personalize_dictionary role.

   The glide.xmlhttp.max_choices system property determines how many choices display on a choice list. This property has a value of 15 by default, however, when the property is not present on the instance, the instance uses a hard coded value of 10.
