Let me assume there is only one level and this cannot be arbitrarily
nested. Also I assume the initial model of this thread:
db.define_table('store_catalog',
Field('maincategory', 'string'),
Field('subcategory', 'string'),
Field('description', 'text'))
t = store_catalog
rows = db(t).select()
from collections import defaultdict
d=defaultdict(list)
for row in rows: d[row.maincategory].append(row.subcategory)
response.menu = [
[T(key), False, None, [[T(sub), False, 'link'] for sub in
sorted(d[key])]] for key in sorted(d)
]
