Radio Button

The radio_tag helper tag generates a radio button. Radio buttons with the same name are part of a set, and only one of them can be checked at a time.

• name: The input's name attribute.
• label: Adds label text next to the radio button.
• checked: Whether or not the radio button is checked. By default, this will be false.
• value: The value submitted to the form when the radio button is checked. By default, this will be "true".
• id: The input's ID attribute. By default this will be set to the name, converted into a variable_name-style string.

Helper Tag

{% radio_tag name: "name", label: "Radio button label!", checked: true, value: "value", id: "id" %}
