The following feature is new to CPQ in this release.
Ability to Pin Option Group Tabs
The Product Configuration page provides an ability to pin the option group tabs. You can switch between an expandable view and a pinned view of the option group tabs. In the Expandable view, you can see a few option group tabs in a single line which you can expand to see all the option groups. Once the tabs are expanded, you can pin them to the page to see all the option at the same time.
