Let us say I am carrying out a site about cars, as well as in the primary content area you will find a couple of sentences in regards to a particular vehicle.

Within the sidebar, are some standard icons. However I likewise want a widget by having an 'info panel' concerning the particular vehicle.

So what is the sanest method of investing in a per-page widget in Wordpress? I suppose ideally the data-panel might be joined through the standard page editing in Wordpress. (or perhaps is this something a plug-in already covers?)

Widget Logic wordpress plugin:

Another Option is to download and install the Graceful Sidebar Widget. This wordpress plugin allows you to produce a sidebar by using content specific to every page or publish. You specify the sidebar content right within the publish edit screen. Hope this can help!

Enjoy! Mike
