Blocks: Overview – Layout
“Old-fashioned” layout, in terms of print media, regards the final arrangement of
information to be displayed to a viewer. It’s how a printed page looks – where images
are, where text columns exist and how they’re broken up, among other visual
elements.
Web page design, naturally, adopted this term as well.
One of the best features of Drupal is its layout versatility. The appearance can be
changed very quickly by changing the theme, but this isn’t the only way to change the
way things look, or the functionality.
Blocks provide the easiest and most robust way of adding and moving things around
on your site: from menus, to images, to add-ons such as Gallery items or Poll results.
First, though, we should get a grasp on just what a Block is…

Blocks: Overview – What Blocks Are
What Blocks are:

Movable groups of content on a web page

Ex: A menu block, a “widget”, a hyperlinked list of content

Note: A Menu will always reside within a Block, but a Block does not have to contain only Menus
How Blocks are created:


Some are created automatically by modules
Others may be created manually
Why Blocks are used:


To establish the layout of a page

Help provide a measure of consistency across a web site

Provide additional functionality

Provide structure and readability to content
To confine content access to particular roles

Blocks: Overview – Layout Regions
Regions are areas on your theme where you can place blocks. These areas are defined
in the theme programming.
Kensington Theme
Carbon Theme
Different themes may or may
not contain different regional
areas, as well as different
quantities of regions. It all
depends on the design.
Take, for example, the
themes at left, both of which
are included in Drupal
Gardens.
Kensington is a three-column
design while Carbon is a twocolumn one.

Blocks: Overview – Blocks Manager
Let’s go to Admin menu > Structure > Blocks
and explore the Blocks manager:
1
1.
The Blocks Manager includes a long,
complex table – at the top, each region
included in the theme is a sub-heading
2.
At the bottom is the Disabled group – these
are blocks that are available but not
currently in use

Blocks: Overview – Block Region Demo
To get a visual idea of how the
regions are laid out, do the
following:
2
1
1.
Click on the Demonstrate block
regions link at the upper left of
the Blocks Manager
2.
When the demo overlay loads,
you’ll see the theme has 20
regions – that’s a complex
theme
3.
3
To close out of the demo, click
the Exit block region
demonstration tab in the
upper left of the screen

Blocks: Overview – Theme Relationship
Block layout is respective to the theme the layout is used with.
If you start with a theme that
has a special region, then
change to a theme that does
not have this region, blocks in
the initial region will disable
themselves because they do
not have a corresponding place
to go to.

In this case, the Carbon theme
doesn’t have a Sidebar B region,
so if you were to change
themes from Kensington to
Carbon, anything in Sidebar B
would be disabled.
Blocks: Basic Configuration
The terms configure and enable are common in IT practices – what do these terms
mean though?
Configure: to set something up so it functions in a desired way. Different
configurations can be applied to blocks to force them to perform in different
ways.
Enable: in Drupal terms, to “turn something on” or make it capable of working.
For blocks to appear on your screen they must be enabled.
In the following exercises, we’ll configure and enable some different default blocks to
see the various ways we can get them to behave.

Blocks: Basic Configuration – Ex. 01 Configure Block Title Visibility
1
A title display is a basic configurable option
that all blocks possess. A block title can be
configured to show the block name, a
different name, or no name at all.
To configure a block title so it shows no
name, do the following:
2
1.
Locate the Book navigation block and click
the configure link
2.
Type <none> in the Block title field
3.
Click the Save block button
Close the Block manager overlay to view
your results.

Blocks: Basic Configuration – Ex. 02 Configure Page Visibility
With every block used in Drupal, the
Page Visibility can be set in the block
configuration. This means that you
can tell your block to appear on the
nodes that you want it to appear on
and “hide” at other times.

Menus: Overview
What Menus are:


An organized list of features or content
Often contains sub-items
How Menus are created:

Standard menus automatically created during Drupal installation




Navigation menu
Primary Links menu
Secondary Links menu
Custom menus can be created manually by all contributors on an OSU Drupal 6 site
Why Menus are used:

To provide organization and clear direction


Users want to “get there” in four clicks or less
A plain website with a great menu system will beat out a beautiful website with a poorly designed menu system
anytime

want them in:
1.
Click on the cross icon next to a menu
item and hold it.
2.
Drag the item to a new position up or
down the list – you can even make it a
child by dragging it to the right, beneath
another item.
3.
Click the Save configuration button when
you are done ordering things.

Menus: Custom Menu Blocks – Overview
Adding items to menus in Drupal 7 is very easy – it can be done right through the
content submission form. Most of the time the user doesn’t even have to go into the
Menus manager.
At some point there may be a need to create a custom menu, though. This could be
for a few different reasons:



More refined content organization
To highlight a specific set of links
To configure a menu block to show only under a certain set of conditions
As mentioned previously, Menus, in Drupal, are always contained within a Block. In
fact, the Menus feature will actually create a block for you.
In the following exercise, we’ll create a custom menu block that contains links to
external websites that relate well to our Food For Thought web site.

Menus: Contextual Menus – Overview
Space is a valuable asset for a web page. The space “above the fold” – which is the
area above the bottom of your screen – is considered prime real estate.
This is why it’s a good idea to make the best use of that space as possible.
Our Book navigation block is a great tool – but we don’t always need it to be there.
Remember, this little collection is really more of an appendix to what will be the
Recipes section of our site.
There is a way to get the Book navigation block to show up only when we need it to by
combining the Page Visibility setting that we’ve worked with, along with the Main
menu that we have at the top of our site.
Let’s find out how to do this.

Beyond Menus: Ex. 06 Most Recent Poll Block – Overview
In the Content Types workshop, we explored how to create the Poll content type.
Poll functionality can be increased by using the Most Recent Poll block, which will
provide your guests and contributors with the ability to interact with your site.
The most recent poll available will automatically show up in a block on your user’s
screen. When the user submits a response to the poll, he or she will then see the
current results of the poll.
As new polls are added to a site, the most recent will show. A link is provided at the
bottom of the block to lead users to older polls they may not have taken.
Let’s take a look at how this works…

Beyond Menus: Ex. 07 Gallery Block – Overview
In the Content Types workshop, we spent some time playing with the Gallery content
type. This great module allows a user the ability to bulk upload images up into the site
and, displays them in an attractive grid and also a lightbox.
The Gallery module does even more, though. It creates a handy block that gives your
user a sneak peek into the gallery.
So now that we know how to work with the content type, let’s get in and see what we
can do with the block as well.

Beyond Menus: Ex. 08 Rotating Banner Image – Overview
The Rotating Banner image is a dramatic, interesting visual addition to the front page.
This contributed module was developed by the folks at Acquia and released to
drupal.org.
The Rotating Banner offers a few different configurable options, including various
transition effects like wiping and fading, dynamic sizing capabilities, and the ability to
create custom inlaid captions and place them in different regions of the banner.
For best layout results, it’s best if the images are at 920 px wide and, while the sizing
can be dynamic, if this option is used, it’s best if the images are close to the same
height.

Summary
We made great progress today! As you’ve seen, blocks allow a user to do so much to
spice up a site. Just as a wrap up, today’s workshop covered:

An understanding of the relationship between Blocks and Themes

Basic block configurations: title, role visibility, and page visibility

An understanding of the relationship between Blocks and Menus

Basic menu use, custom menu configuration, and how to create a contextual menu

Configuration of the Poll, Image Gallery, and Rotating Banner blocks
