In WP2, sites were designed with a block structure, rather than a full-width structure.
To add content to these regions, they were added using blocks. Blocks were most commonly configured to the Sidebar and Postscript regions. This section relates specifically to generic blocks – a generic block offered users a single WYSIWYG body field do add content. Any content that could be added to a basic page could be added to a generic block.
Generic blocks were added to WP2, by going to Structure > Blocks > Add Block. Users could then add any content they wished to the WYSIWYG editor and would select a region to configure the block to. Once the block was configured to the page, it was immediately visible on the live version of the site (i.e., no content revisions). It could be configured to appear on all pages, or a single page.
Migrating to WP3
When migrating content from generic blocks, you’ll need to review the type of content that the block is being used to display and identify a paragraph that would fit the content well.
If the block displays a series of quick links, or downloadable files, it may make sense to transfer the content to a Link Set paragraph.
It will be up to your discretion to identify the paragraph that you believe will fit the content best. In terms of placement on the page, content in the sidebars (particularly the left sidebar, or ‘sidebar first’) is often added to call it out from the page content and draw the readers’ eye – you’ll want to keep content toward the top of the page. Content that was in the postscript region should be kept at the bottom of the page.
If the block is used on multiple (or all) pages on the site, you can decide whether the equivalent WP3 content also needs to be placed on all pages.
