SebElement

Seb version of Selenium WebElement.

Module

Module is similar to SebElement. However unlike SebElement, Module can contain multiple other SebElements/Modules. To define some simply extend Module class and define its elements same as you would on PageObject. Other than that, you can treat it like normal element. You can use it on any page or module:

@FindBy(id = "header")
protected HeaderModule header;

Or find it by using method .findOne(By.id("header"), HeaderModule.class).
