Topol Plugin Guide

Appearance

Changelog - March, 2025 ​

New Features ​

Lambda Region ​

The Lambda Region setting specifies the AWS region where your Topol Plugin’s serverless Lambda functions run. This determines the physical location—either Frankfurt (eu-central-1) or Northern Virginia (us-east-1)—where your backend logic executes.

Why It Matters ​

Choosing the nearest region minimizes network round-trips, so your templates render faster and your API calls complete with lower latency. At the same time, selecting a European data center can simplify compliance with GDPR or other local data-residency rules, while a U.S. region may better suit North American workloads.

How To Enable ​

Add or update the lambdaRegion key in your TOPOL_OPTIONS. If you don’t set it explicitly, eu-central-1 is used by default:

ts
  lambdaRegion: "eu-central-1", // "eu-central-1" for Frankfurt
                                // "us-east-1" for N. Virginia

For full details on configuring this feature, see our documentation.

Hover Preview for Saved Blocks ​

You can now get an instant visual preview of any saved block by simply hovering over its thumbnail in the Premade Blocks panel. A lightweight pop-up window will display the block’s full rendering—complete with content and layout—without the need to drag it into your canvas first.

Why It Matters ​

Being able to inspect a block’s actual appearance before insertion eliminates guesswork and reduces trial-and-error iterations. Designers can scan through dozens of saved components, instantly spotting the right header, footer, or call-to-action without cluttering their editor workspace.

Improvements ​

New Configuration Option for Merge Tags ​

You can now swap out the default merge-tag sets on the fly by calling window.TopolPlugin.setMergeTags(yourMergeTagsArray), letting you load different tag groups at runtime without rebuilding the plugin. For full details, see our documentation.

Replaced Missing Images in Premade Templates ​

Several premade templates were displaying broken or missing images. As a temporary measure, we’ve swapped in a universal placeholder for every missing asset. We’re working on a full review of our Premade Templates to deliver a permanent fix soon.

Improved Border-radius Settings ​

You can now define a single border-radius value to apply uniformly to all four corners of a Content Block, or specify each corner’s radius independently (top-left, top-right, bottom-right, bottom-left) for fully custom shapes.

Inner vs. Outer Column Offsets ​

You can now choose whether a column’s offset applies inside its own padding (inner offset) or outside its container (outer offset), giving you precise control over how columns shift relative to their content and neighboring blocks.

Bugfixes ​

  • Fixed an issue where removing the link from a Video block left an empty, zero-dimension placeholder in the template.
  • Resolved a bug where deleting the text label of a Button block caused it to collapse to zero dimensions while still remaining in the template.
  • Resolved an issue where HTML conditional comments inside an HTML Block were incorrectly flagged as invalid code.
