I'm not sure what exactly you want to achieve but here is an example:

Field selection type definition (old API):

'questions': fields.selection([('1','question 1'),('2','question 2'),('3','question 3'),('4','question 4'),('5','question 5') ],'Choose one'),

or

you can create/add a class (as example banners which is a class related to model "product" so you can change it to your own model)

#============= B A N N E R S ===============

class product_banner(orm.Model):

_name = 'product.banner'

_columns = {

'name': fields.char('Banner'),

'banner': fields.binary('Image file'),

}

class product_template(orm.Model):

_inherit = 'product.template'

_columns = {

'product_banner_id': fields.many2one(

'product.banner',

'Banner', help='Display Banner on product image', ondelete='restrict'),

}

will be fully editable  so you can change/add more if needed.

You'll need field of type "selection" for that.
