Selenium Exception Element is not visible

Question

My task is to write a parser for clicking a button on a website. There are a lot of buttons, but my problem is only clicking on one of them. The source htmlcan be found here: http://pastebin.com/XhsedGLb

And my python code is:

 driver = webdriver.Firefox()  
 ...
 el = driver.find_element_by_id("-spel-nba")
 actions.move_to_element(el)
 actions.sleep(.1)
 actions.click()
 actions.perform()

The error I get is this:

ElementNotVisibleException: Message: Element is not currently visible and so may not be interacted with

According to Saifur, I just tried waits with the same element not visible exception:

wait = WebDriverWait(driver, 10)
wait.until(EC.presence_of_element_located((By.XPATH, "//input[contains(@id,'spsel')][@value='nba']"))).click()

Answer 1

Finding the element before locating the one with the issue solved it for me (that is, just before it in terms of tab order). After that, calling Tab on that element also helped.

from selenium.webdriver.common.keys import Keys
elem = br.find_element_by_name("username")
elem.send_keys(Keys.TAB) # tab over to not-visible element

After that, I could perform any actions on that element.
