Graph concept

We reccommend use to graph concept and direct mapping on DOM document

For example

from pagium import Page, PageElement, WebElement, By, controls

class MyPage(Page):
    __path__ = '/'

    class Header(WebElement):
        class AuthForm(WebElement):
            username = PageElement(controls.Input, by=By.NAME, value='username')
            password = PageElement(controls.Input, by=By.NAME, value='password')
            submit = PageElement(by=By.TAG_NAME, value='button')

        auth_form = PageElement(AuthForm, by=By.TAG_NAME, value='form')

    header = PageElement(Header, by=By.CSS_SELECTOR, value='[class*="header-wrapper"]')

with MyPage(wd, 'http://project') as page:
    page.header.auth_form.username.fill('username')
    page.header.auth_form.password.fill('password')
    page.header.auth_form.submit.click()
