Monklets are predefined code snippets that allow you to bring in other module content (sermons, events, etc.) into your pages.  There are a few monklets that have been created that are placed in the content area of your sidebar sections.

You can use a monklet inside a section by placing your cursor in the content area, selecting Insert > Insert Monklet > "Desired Monklet".

Some monklets allow inline parameters to be passed to define items from a specific group, category, etc.  http://help.monkcms.com/article/using-monklets/ and https://help.ekklesia360.com/article/using-inline-parameters/ provides details on using these parameters.

*NOTE - Monklets that are defined with "Sidebar Monklet" in the title can only be inserted into the content area of a sidebar section.

There are 2 sidebar monklet options you can use for your sidebar sections.  

Sidebar Monklet - Recent Sermon (Video): Displays the most recent sermon. You can use the find_group and find_category inline parameters as needed.

Sidebar Monklet - Featured Events:  Displays the four most recent events published as featured. You can use the find_group and find_category inline parameters as needed.  The first event is the only event that will show an image (if one is assigned).
