Ok, thanks for the answer. It is now clear.

The "zero" option is intended for single-selection drop-downs to allow
the user to make no selection. This is not necessary for
multiple-selection inputs because it is already possible to make no
selection simply by not clicking/checking any of the options.

Hello web2py community,
I have a multiple select widget:
db.PRODUCT.class_of_compounds.requires=[IS_EMPTY_OR(IS_IN_DB(db,
db.CLASS_OF_COMPOUNDS.id <http://db.CLASS_OF_COMPOUNDS.id>,
label=db.CLASS_OF_COMPOUNDS._format,
multiple=True, sort=db.CLASS_OF_COMPOUNDS.label, zero='choose'))]
The "zero" field does not appear. If I change multiple from True to
False it appears.
I have probably missed something in the documentation...
How can a user then unselect an item ?
Regards,
Thomas
