ynzero

DESCRIPTION

The ynzero widget creates a simple "Yes or No" option.

The actual widget titles, "Yes" and "No", are locale-aware so adding their translated versions to the locale database will be enough to have them adjusted to visitors' language settings.

A negative answer will return value 0 (false) to the application.
A positive answer will return value 1 (true) to the application.

EXAMPLES

Example: 'Yes or No' widget, rendered as a dropdown list

[display name=example type=ynzero]

Example in action:

Example: 'Yes or No' widget, rendered as a "radio" button

[display name=example type=ynzero variant=radio]

Example in action:

               No Yes

NOTES

The widget is created by Interchange's Vend::Form::yesno function. Passing attribute type="yesno radio" to it is equivalent to passing attributes type=yesno variant=radio. However, only method type="yesno radio" is available if the widget is invoked through the [widget] tag and ITL.
