Dialog list in web with @dbcolumn

I’m using a field type dialog list with this selection:

_Lookup := @DbColumn(“”;“”:“”;“(LKP_Wine)”;1);

@If(@IsError(_Lookup); “”; @Unique(_Lookup))

In Notes client the field is empty in a new document with the option to select a keyword.

But in a web client the drop down list is initialized with the first vaule of the lookup. No way for the user to leave the field emtpy. Is there a way to add an entry “-None-” to the dialog list?

Subject: Like this

_Lookup := @DbColumn(“”;“”:“”;“(LKP_Wine)”;1);

@If(@IsError(_Lookup); “”; “-None-”:@Unique(_Lookup))
