Introduced in SiteFarm 5.0.0, the Priority Link blocks seek to offer a way to mimic a very popular presentation of the main links on the UC Davis' home page.
There you are, building your site, and you come across a page where there's a noticeable space either before or after your main content in the First or Second Sidebar region.
What's going on here? And, more importantly; how do you fix it?
One of the powerful benefits of using a content management system like Drupal is the ability to reuse the blocks available in the service, but reusing your blocks can mean a couple different possibilities:
In instances where you have a special configuration in mind, will be attaching multiple blocks at one time, and/or defining your preferred order of blocks from top to bottom or left to right, using the Block Layout page is the recommended approach.
Please be advised that this feature can only bet set by a person with the Site Manager role.
These two regions are part of the default templated page region layout and are located above and below the Content region respectively, and can be configured to output more complex, custom layouts as described here.
