I have custom post types created in my wordpress installation and needs to show a specific widget in the sidebar of a specific post-type item (single). Is this possible with Restrict widget?
Yes, this plugin can handle that via UI in your widget area.
If you need some extra control there’s a filter that allows you to set any display conditions you can imagine in WP (http://www.dfactory.eu/docs/restrict-widgets-plugin/filters/rw_display_widget/)
Thanks Bartosz for answering faster than a blink of an eye :-)
I missed the filtering alternative in the documentation and that will exacly solve my challange, so again thanks alot!
