Aliastag Form Field

The aliastag form field type provides a list box containing specific language definitions. It does this by getting a unique list of components and objects from #__contentitem_tag_map and then extracting the language definitions for each entry, i.e. it gets "com_content.article" from querying #__contentitem_tag_map and then splits it into com_content and article and looks for COM_CONTENT_TAGS_ARTICLE="Article" in the administrator language com_content.sys

• type (mandatory) must be aliastag.
• name (mandatory) is the unique name of the field.
• label (mandatory) (translatable) is the field html label.
• description (optional) (translatable) is the field description.
• multiple (optional) if set to true allows multiple items to be selected at the same time. Set to false to allow single selection.
• required (optional) if set to true, the first field option should be empty, see last example.
