In reading Mastering SAP BusinessObjects Design Studio with SAP NetWeaver BW, I learned about hiding components, and checked out this feature on one of my existing applications
First I select a component, select right-click, and then Hide
Then you do not see the component when designing the application.
Notice it has a red strike next to it.
To bring it back, simply select right click on the component and select Show as shown above.
At 432 pages, this book has several new things for me to learn.
