There are two different issues. One is the question in your first email 
about migration. Is the problem that you do not get a dropdown? Is it 
possible you manually set a validator for the field?

Your second question. How to drop a table.
1) enable migrations
2) python web2py.py -S yourapp -M -M
3) type

db.yourtable.drop()
db.commit()

4) edit the model and remove the table before using the app, else it will 
be created again.
