Hi Mark,
You must understand that each Widget in :
widgets = (
forms.TextInput(attrs=attrs),
forms.TextInput(attrs=attrs),
forms.TextInput(attrs=attrs),
)
Has a *render()* method that return html of widget. You must only
concatenate each html of widget. You can use *format_output* like this:
def format_output(self, rendered_widgets):
widget_a = rendered_widgets[0]
widget_b = rendered_widgets[1]
widget_c = rendered_widgets[2]
return "%s %s/%s" $(widget_a, widget_b, widget_c)
I hope that solution above be that you want, but if you want customizing
html/css/javascript of TextInput widget, you must override render() method
of forms.TextInput widget.
Cheers.
