Making a block sticky in a category in Moodle

You can make blocks sticky at different levels in Moodle:

• Sitewide
• Homepage
• Category
• Course
• Activity/Resource

To make a block sticky in a category you just need to navigate to the category and add the block, once added you need to "configure the blog" and in "Page context" choose

1. "Display on category..."
2. "Display on category and any pages within it"

Protecting blocks from deletion

Note: To delete a block completely, in addition to uninstalling it on the blocks page, you also need to remove/delete the actual block folder from the moodle/blocks folder, otherwise Moodle will reinstall it next time you access the site administration.
