Catalog files registered in the standard catalog browser can be separated and displayed independently from the catalog browser.
The separated catalog can be docked to any position—top, bottom, left, or right.
However, it cannot be overlaid on the Scene Browser.
It can be docked next to the Scene Browser for display.
If you no longer need the separated view, you can return it to its original position in the standard catalog browser to restore the initial layout.
Please refer to the video below.
