for SQLFORM and CRUD, if the field is of type list:reference <type>, a default multiselect widget is displayed. You can use your own custom constraint with IS_IN_DB(<args>). For other type of forms you might want to use the helper classes for build them
mycustommultiselect = SELECT(*[OPTION(option[0], _value=option[1]) for option in tuple_sequence], _name="mycustommultiselect") where tuple_sequence is a list of (name, value) tuples On 18 mar, 09:21, Hassan Alnatour <[email protected]> wrote: > Dear ALL, > > I want To create a multi-Select Field , how can i do that ??
