To add your designs, you just need to pass an array of designs during plugin initialization. To understand how a design object should be formed, refer to the following example:
var options = { designs: [ { "src": "url", "name": "My first design", "categories": ["Category 1", "Category 2"], "price": 2, "parameters": {} }, { "src": "http://localhost:8080/designs/Be_a_unicorn_in_a_field_of_horses_6105.svg", "name": "My second design", "categories": ["Category 2"], "price": 3, "parameters": {} } ] } var instance = new AsukaDesigner('#myId', options); // Create an instance of the main plugin class
