I'm hesitant to commit another widget right this moment, because there are some good suggestions for API cleanup ongoing from David Bernard and Michele Cella. Now is really the last chance to do that kind of cleanup. I'd rather not combine the value with the set of options. You should be able to pass another keyword to insert() to hold the options list. And, the main select widget can probably support both styles of working: up-front definition and render-time definition.Yes, that's exactly how I've done it. Any widgets can provide additional options using a constructor argument (options) and the same argument at render/insert time. For a selection widgets those options are managed as the possible choiches. Ciao MicheleThanks for the patch and ticket... we do need this in some form, without question... (I *think* the current widget may take a callable for the options list, which is the current mechanism for handling this, but that's not always as pleasant.)

If not then I'll add it as a recipe for a custom widget on the wiki. (Copied from the ticket) Sometimes you don't know what a SelectField's options are going to be before you .insert() it and changing the options on the fly isn't threadsafe. Attached is a patch with a new widget called DynamicSelectField?. It's essentially the same as a normal SelectField? except it pulls out it's options from widget_value on .insert(). Examples: <div> ${testwidget.insert(value=(3, [(1,"Apple"),(2,"Banana"),(3,"Pear")]))} </div> <div> ${testwidget.insert(value=(2, [(1,"Audi"),(2,"VW"),(3,"Ford")]))} </div> The first argument in the value tuple is the value of the option you want to be selected and the second is a list of tuples containing the options and their respective values and text. With this method the data can still be passed when the widget is nested in a Form Widget (or subclass thereof).
