How do I use it only in the frontend theme? Using the jQuery Update module, I set version 1.8. This version "broke" the views UI in the Admin theme; it seems that the AJAX calls in the Views UI work only with jquery 1.5.

How can I fix it?
With jQuery Update 7.x-3.0-alpha2 and later, there is a setting that allows to change the jQuery used for a specific theme; you can select:


The site default version (set with the jQuery Update module)
The version that comes with Drupal
Any version supported by the jQuery Update module
