Thesis-OpenHook gives you access to 55 hooks altogether, which include the WP-Header and WP-Footer hooks – parts of the page that aren’t displaid to viewers, but contain the META tags and other scripts that the search engines or browsers use.
All I’ve done is add the content I want to display, and a bit of in-line CSS to style it, to the box against the Footer hook. Just as if I was writing a normal HTML page.
In this video tutorial explains about how to add categories directly to the footer whole width. You can add your categories first part of the footer or middle or at last. By using the corresponding hook you can place anywhere in footer. By default thesis footer is having thesis attribution and wordpess admin function. If you don’t want these functions you can remove by using hooks.
Click the Footer Hook and paste the content you created for your footer into the box that comes up. Check the ‘Execute PHP on This Hook’ check box and hit the ‘Little Save’ button.
