## html
Tag radio

Render A Radio Button Input Field

Renders an HTML <input> element of type radio, populated from the specified property of the bean associated with our current form. This tag is only valid when nested inside a form tag body.

If an iterator is used to render a series of radio tags, the idName attribute may be used to specify the name of the bean exposed by the iterator. In this case, the value attribute is used as the name of a property on the idName bean that returns the value of the radio tag in this iteration.
