In this how-to guide, we will be going over how to share a block's settings between instances of a block on more than one page.
This is like adding block to your template, except that it does not need to be in the header or footer. It will not be on every page of the site, only the pages you put it on.
Navigate to Site Designer. If you are not already editing your live theme, click the edit (or continue editing) button to open your theme.
Add a block to the page, or edit an existing one that you wish to appear on more than one page.
Flip the switch labeled "Make this block reusable."
Warning: Once you make a block reusable, it will remain reusable and cannot switch back. If you want a unique copy of this block, you may add the same block again. This is an experimental new feature—we want to hear from you if this becomes a problem.
Use the "Page" dropdown in the header to edit another page, or add a new one.
Click the plus icon to begin the process of adding a block. Notice that you are viewing the "Default Blocks" tab—click on the "My Blocks" tab.
Click on the configuration icon to the left of the name of the block you made reusable. Select Rename from the menu. Enter a new name and submit the form to save it.
Click on the name of the block to add it to the page.
When you edit the block, you will see it has the same settings as on the previous page. If you make changes to the block from any page, those changes will appear on all pages that share the block.
