This is an RFE. Description of problem: bugzilla supports Javascript as a way to narrow down release numbers based on product selections. Featurezilla omits this feature. Featurezilla should support Javascript so that appropriate version numbers are guaranteed for product selections.
This is not possible. On the Featurezilla query screen (almost same as Advanced normal query) there is only one product selected by default which is Feature Tracker. So the Product Release and Target Milestone fields will not update with the use of Javascript. This is similar to the normal Advanced Bug query screen with javascript enabled and selecting the Feature Tracker product.
