Not sure I got the heading understandable, but this is what I want to achieve (actual values only for demonstration, the app is not about cars :-)):
Given a table: db.define_table('cars', Field('maker','string'), Field('model', 'string'), Field('colour','string')) db.cars.maker.requires=IS_IN_SET(('Volvo','VW','Chrysler')) db.cars.model.requires=IS_IN_SET(('V50','S60','Passat','Voyager')) db.cars.colour.requires=IS_IN_SET(('blue','red','pink')) How can I present a form to the user where the drop downs depend on each other, i.e. if the user selects a make (Volvo) the next drop down only shows the relevant models (V50, V60) and selecting a model populates the colour drop down with the available choices? I've looked at an example from web2pyslices<http://www.web2pyslices.com/article/show/1410/cascading-drop-down-lists> but in my case I want to store all the choices made (maker, model, colour), not only the final value as in the example (in that case, the area code). Should I be able to adapt the example for my purposes? Regards, /Stefan
