Filters can be used to add links, insert multimedia players, convert Mathematical expressions or emoticons into images and more.

A filter may be enabled at the site level and then removed as needed at the course or activity level. Thus a teacher can disable glossary auto-linking in a quiz for example.

Standard filters

Filters in LMS include:

• Activity names auto-linking – Scans course text for activity titles that exist in the same course and creates a link to them
• Algebra notation – Convert algebra code into images
• Convert URLs into links and images – Converts URLs in selected formats, such as LMS auto-format, to click-able links
• Database auto-linking – Enables automatic linking of course Database activity entries
• Display emoticons as images – Converts textual emoticon (smiley) characters into images

• FontAwesome – This scans text for icons that can be embedded using the FontAwesome icon set.

• filter generico – gives you considerable ability to customize your LMS site without having to resort to multiple plugins, or custom PHP coding
• filter multiembed – Facilitates embedding of third-party content from a growing list of service providers (e.g. Prezi, Haiku Deck, etc.)
