Selecting two options in the drop down menu with Selenium + Python does not work

Question

from selenium import  webdriver
from time import sleep
from urllib.request import Request,urlopen
import pandas as pd
from selenium.webdriver.support.ui import Select        
from selenium.webdriver.support.ui import Select  

url = "https://www.viprbrc.org/brc/vipr_genome_search.spg?method=ShowCleanSearch&decorator=flavi_dengue"
browser = webdriver.Chrome(xxxx)
browser.get(url)
sleep(20)


box_drp_x= browser.find_element_by_id("hosts").click()
box_dpr = browser.find_element_by_id("hostsBox")
human_host = Select(box_drp)
human_host.select_by_value("Human")

How do I select two options in the drop down menu (Human and Mosquito)? My code runs but does not select, which may be occurring?

Answer 1

Good afternoon, I’m a python beginner and tried several ways to use the select option but I did not succeed because he insists that the button is not visible or can not interact with it, but with the following code I was able to type the two options in the field and select them:

from selenium import webdriver
from time import sleep
from selenium.webdriver.common.keys import Keys

url = "https://www.viprbrc.org/brc/vipr_genome_search.spg?method=ShowCleanSearch&decorator=flavi_dengue"
browser = webdriver.Chrome()
browser.get(url)
sleep(3)
browser.find_element_by_xpath('//div[@id="hosts"]').click()
input_field = browser.find_element_by_xpath('//input[@value="Choose a Host..."]')
hosts = ['Human', 'Mosquito']

for value in hosts:
    input_field.send_keys(value)
    input_field.send_keys(Keys.ENTER)

First of all I clicked on the div hosts and with it using : Selenium.webdriver.common.Keys I sent the texts Human and Mosquito to the input field pressing Enter right after, apparently something hides the actual selection.

EDIT

The problem of not being able to select select I believe it is because it is with the "display-style: None", even if I run to change it to "block" it can not make the selection, looking better the source saw that the selection actually occurs here:

What you can see with this code:

from selenium import webdriver
from time import sleep

url = "https://www.viprbrc.org/brc/vipr_genome_search.spg?method=ShowCleanSearch&decorator=flavi_dengue"
browser = webdriver.Chrome()
browser.get(url)
sleep(3)
menu = browser.find_element_by_xpath('//div[@id="hosts"]')
menu.click()
hosts = menu.find_elements_by_xpath('//div/ul/li[@class="active-result"]')
for value in hosts:
    if value.text == 'Human':
        value.click()
    else:
        pass

In this second example you would need only change to click the two values
