I'm learning Drupal and am trying to wrap my head around it. Recently I have been studying Panels. I wanted to see if my understanding of it was correct.
Basically, you use panels for different layouts: 1col, 2cols, 3cols, etc. You can add or apply different content to each of these columns (aka regions?), eg: a node, custom content, a block, widget, form, etc. You can drag and drop where you want these to be within your layout.
You can either set up a 'panel' as a page, by going Structure>>Panels>>Panel Page
Or, you can make turn an existing page (node?) into a panel page by going Structure>>Pages>>Enabling Node view then creating a 'variant' with a Node type specific to the node (page?). We can then select a layout and place elements from the node in panel's regions, like above.
So the reason to use Panels is to simply allow you to place elements, nodes, blocks, widgets, etc in multiple region layouts.
Is this correct?
