Definitions

Another input filter approach to adding functionality - in this case, it adds the facility to have explanatory text related to terminology that comes up in your content. To get this working you start by creating your definitions and then attach the definitions filter to an input format.

For example, you might create a list of module names as terms to be defined so you have one called ‘entity_translation’ and give it the definition ‘module for extending translation to fieldable entities in Drupal Seven’. Now go to input formats and add the ‘Definitions’ filter to a format such as ‘filtered html’. Now if you create an article with that format and use the word ‘entity_translate’ you’ll find on saving it that the term if given markup like this entity_translation If you also enable the qtip module these will appear as tool tips.
