Checkboxes, radio buttons, and menus

Contact Form 7 provides several types of form-tags for representing checkboxes, radio buttons, and drop-down menus. This article explains about the usage and semantics of these form-tags.

Checkboxes and radio buttons

Both checkbox and checkbox* represent a group of checkboxes (<input type="checkbox"> in HTML). checkbox* requires the user to select at least one of the boxes.

radio represents a group of radio buttons (<input type="radio"> in HTML). Because a group of radio buttons is naturally required, a radio form-tag works as a required field. It is advised to preselect an option in a radio button group using the default:1 option.

OptionExamplesDescription
id:(id)id:fooid attribute value of the wrapper element.
class:(class)class:barclass attribute value of the wrapper element. To set two or more classes, you can use multiple class: option.
default:(num)default:2
default:1_2_3
Preselected options. The integer following default: is the position in the order of items. 1 is the first one. If you want to make two or more items selected, joint integers with underbar (_), as default:1_2_3.
label_first By default, a checkbox or a radio button are put first, and a label last. By adding label_first option, you can reverse them.
use_label_element Wrap each checkbox and radio button with <label> tag.
exclusive Make checkboxes exclusive. This means, when you select a checkbox in a group, others will be cleared, so the group accepts the zero-selected or one-selected state only. This is a JavaScript gimmick so doesn’t work without JavaScript. radio form-tags don’t support this option.
free_text Append a free input text field to the last item.
data:(name)data:countriesGet the values from Listo.

These types of tags have one or more values, and the values will be used as the values and labels of the checkboxes or radio buttons.

Example:

[checkbox your-country "China" "India" "San Marino"]

Drop-down menus

Both select and select* represent a drop-down menu (<select> in HTML). select* requires the user to select at least one option from the menu.

OptionExamplesDescription
id:(id)id:fooid attribute value of the select element.
class:(class)class:barclass attribute value of the select element. To set two or more classes, you can use multiple class: option.
default:(num)default:2
default:1_2_3
Preselected options. The integer following default: is the position in the order of items. 1 is the first one. If you want to make two or more items selected, joint integers with underbar (_), as default:1_2_3.
multiple Make the drop-down menu multi-selectable.
include_blank Insert a blank item into the top of options of this drop-down menu.
first_as_label Use the first value as a label.
data:(name)data:countriesGet the values from Listo.

These types of tags have one or more values, and the values will be used as options in the drop-down menu.

Example:

[select your-country "China" "India" "San Marino"]
