Managing bundles
The bundles screen allows you to search, filter, create, edit and delete Stash bundles (variable categories), and clear all variables assigned to a specific bundle.
Stash has three default bundles which are non-editable, these are identified with a lock icon.
Create your own bundles to help organise your variables and provide a target for cache-breaking rules. Use a unique name for custom bundles that you can reference in your template tags with the bundle="my_bundle" parameter.
Bundles are NOT site-specific, so if you are using the Multiple Site Manager the bundles you create will be available to every site. Variables assigned to bundles ARE site-specific, and when you clear variables in a bundle they are cleared for the current site only.
