(Quick Reference) # 8.3.5 Tag Namespaces Version: 3.2.8 ## 8.3.5 Tag Namespaces By default, tags are added to the default Grails namespace and are used with the `g:` prefix in GSP pages. However, you can specify a different namespace by adding a static property to your `TagLib` class:
    class SimpleTagLib {
        static namespace = "my"

        def example = { attrs ->
            ...
        }
    }
Here we have specified a `namespace` of `my` and hence the tags in this tag lib must then be referenced from GSP pages like this:
    <my:example name="..." />
where the prefix is the same as the value of the static `namespace` property. Namespaces are particularly useful for plugins. Tags within namespaces can be invoked as methods using the namespace as a prefix to the method call:
    out << my.example(name:"foo")
This works from GSP, controllers or tag libraries | Quick Reference (hide)
