One of the key components on MegaEdit is the Canvas. In the design world, the canvas represents the dimensions of the product.
Once you have created your Dynamic (MegaEdit) Product you will need to go to Catalogue > Product Types > MegaEdit > MegaEdit Canvas > and click Add New:
You will then be directed to a new page where you can configure your canvas:
Name: Name of the Canvas. For example: A4 Portrait
Select a preconfigured dimension (optional): If you are unsure about the dimensions, you can use one of the predefined dimensions
Unit: Measurement unit
Width: Width of the canvas depending on the unit selected
Height: Height of the canvas depending on the unit selected
Manage Dynamic Product Canvas
Within this page, you will be able to see all the canvases created by storefront administrators. You will be also able to Add, Edit or Remove canvases. There is also an advanced setup to allow customers to create their own canvas dimensions rather than picking a pre-existing one.
