Beginning Drupal 8

Chapter 10 ■ Creating Pages
At this point all of the blocks that are defined to be site-wide blocks will appear on the page, along
with the article for DrupalCon. But what if you wanted more things to display on this page other than the
standard blocks and the article? The answer is to use Views to generate blocks from content, or use the block
interface to create or assign a block to appear on this page. Let’s begin by creating a custom block through
the “Block layout” page and assigning that block to appear only on the DrupalCon page (see Chapter 8 for a
refresher on blocks):
1. Click the Manage link in the top menu followed by the Structure link in the
secondary menu. Click the “Block layout” link to display the “Block layout” page.
2. Click the “Add custom block” button to create a new custom block.
3. In the “Block description” field, enter “DrupalCon 2015 Los Angeles.”
4. In the Body field, enter “May 11-15, 2015 in the Los Angeles Convention Center.”
5. Click the Save button.
6. On the “Configure block” page that appears, locate the Region select list and
set the region to “Featured top” (if you are not using Bartik, select another
prominent region).
7. To restrict which pages this block will appear on, click the Pages tab in the
vertical navigation bar and, in the Pages text area, enter the URL associated with
the article you created, starting with /node. For my example, it’s the first article
that I’ve written on the site, so the value that I will enter in the box is /node/1.
Next, click the “Show for the listed pages” radio button, as we only want this
block to appear on our article’s page.
8. Click the “Save block” button to save the new block, and then navigate back
to the article page that you are working on by clicking the Content link in the
secondary menu and clicking the title for the article in the list of content.
After adding the block you should see something similar to Figure 10-2.
