Starting with version 3.0, the module supports most of the K2 Extra Fields types (the relevant ones).

The supported types are:

• textfield
• textarea (limited ^*)
• select
• multipleSelect
• radio
• link (no popup)
• date

^* The textarea type handles the following html tags:
<b> <i> <tt> <abbr> <acronym> <cite> <code> <em> <strong> <a> <br> <img> <q> <span> <sub> <sup>

Once the fields are created in the K2 component, they are made available in the information blocs:

When selected, the field's value will show for the item in the module, if the item has a value for the field.
