Python Flask WT-Form MultiCheckboxField Demo: Five Guys use checkboxes to choose toppings

Показать описание
In this video we modify our previous WT-Forms "Five Guys" example. We convert the MultipleSelectField (that allows the user to make more than one choice -- in this case multiple topping such as ketchup, mustard, and barbeque sauce) into a MultiCheckboxField. Behind the scenes the two approaches have the same effect -- the user passing an array of values which we use the getlist() method to process. We work through the widget import to extend the MultipleSelectField into the MultiCheckboxField.
