Download and unzip the right version of the Chromium driver from here and place it in your working directory.
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
driver = webdriver.Chrome(executable_path='./chromedriver')
url = ...
driver.get(url)
menu_xpath = '/html/body/root/sidebar/div/ul/li[1]'
menu = driver.find_element_by_xpath(menu_xpath)
hover = ActionChains(driver).move_to_element(menu)
hover.perform()Then, if you're on a Mac, you can press fn+F8 to freeze the submenu, and
inspect its elements in the developer console. Once you have the next xpath,
you can click on it,
submenu_xpath = '/html/body/root/sidebar/div/ul/li[1]/sidebar-item/ul/li/ul/li[1]'
submenu = driver.find_element_by_xpath(submenu_xpath)
submenu.click()
