There is 2 types of selected boxes:

  1. Unique choice
    allow the user to select one unique items in a list of options.

  2. Multiple choice
    allow the user to select one/multiple items in a list of options.

    Used if you need a recognizable image to help to make a choice, like famous brands for exemple.

  2. Image as content
    Used if you need to bring some illustrative information about the product to help visually to make a choice.

Keep consistency

If you use an image in a selectable box, then you must put some in each one for the same question to keep consistency.


With icons

Icons can be used as a label or in addition to the text label when you need a recognizable visual to help to make a choice, like product icons for exemple.

Keep clarity and consistency

Be careful that the icon must be obvious and bring clarity and not questioning.
If you use an icon in a selectable box, then you must put some in each one for the same question to keep consistency.

HTML / CSS

Selectable box , are built with <input type='radio'> or <input type='checkbox'> and a <label> to be able to click the whole box to select it.

Block elements are forbidden inside of the selectable box

As the content of the box is inside of the <label> , we cannot put any block element like <p> , <ul><li> ,...

To simulate a <p> , we use <span class='rs-sbox-block'>Text of the paragraph</span>

Accessibility

Multiple Selectable boxes must be wrapped in a <fieldset> containing a <legend> .
<legend> can be visually hidden and showed only for screen reader by show-for-sr class.

Single selectable box must make sense from their labels.
We put ac- prefix (abbreviation for "accessibility") to know that this id has been added for accessibility matter.

Optional selectable box must be specified in the <legend>

To use Zurb Foundation form check javascript, data-abide="ajax" attribute should be added to <form> so error class will be added/removed dynamically when needed, for example if <input> is required.

Accessibility

The error message <span> should have an id (prefixed with "ac-" as accessibility abbreviation to know this is added for accessibility matter) which should be referenced in the <input aria-describedby="error_id"> for screen readers when the error is displayed. This is automatically added by the javascript.
