There are three types of positions:
- The "all" position will make the widget show up in the sidebar of all pages.
- Or you can input a comma separated list of templates that need the widget. Popular templates: forum_list (the index page), forum_view (the individual forum page), thread_view (the thread page).
- Or you can input a comma separated list in the format of "hook:hook_name" to render the widget directly to the hook. For example: "hook
age_container_content_top" will make the widget visible at the top of the page, on every page.
You can browse the site with templates and hooks information here.
