Hi,

the select type custom fields sadly don't use the description at all.
But if you switch the type for the custom field to "Enter one value with
autocompletion", the autocomplete list displays "Name (Description)".
Maybe this is an option for you.

it's working as intended, but if you have a bit of perl knowledge, you
should be able to quickly add the description in
share/html/Elements/EditCustomFieldSelect.

example:
- ><% $name %></option>
+ ><% ($value->Description) ? $value->Description : $value->Name %></option>


if you wan't to show the description on an already assigned field, you
have to add a "ContentDescription" method in
local/lib/RT/ObjectCustomFieldValue_Local.pm that will filter on the
current CF Name assigned to object and get Description from CF values.
Something like:


------ snip ------
package RT::ObjectCustomFieldValue;

use strict;
no warnings qw(redefine);

sub ContentDescription {
my $self = shift;
my $content = $self->Content;
if ( grep { $self->CustomFieldObj->Type eq $_ } qw( Select Combobox ) ) {
my $Values = $self->CustomFieldObj->Values;
$Values->Limit( FIELD => 'Name', VALUE => $content );
if ( $Values->Count && $Values->Count == 1 ) {
my $Value = $Values->First;
$content = ( $Value->Description ) ? $Value->Name.' ('.$Value->Description.')' : $Value->Name;
}
}
return $content;
}

1;
------ snip ------


Then use this method mainly in share/html/Elements/ShowCustomFields.

- $m->out( $m->interp->apply_escapes( $value->Content, 'h' ) );
+ $m->out( $m->interp->apply_escapes( $value->ContentDescription, 'h' ) );



Be warned that if you deleted a value in the CF, matching objects will
not be able to find the matching Description.
