web scraping gives only first 4 elements on a page-CodePudding

I tried to scrap the search result elements on this page: https://shop.bodybuilding.com/search?q=protein bar&selected_tab=Products with selenium but it gives me only the 4 first elements as a result. I am not sure why? it is a javascript page? and how can I scrap all the elements on this search page? here is the code I created :

import requests
import numpy as np
import pandas as pd
from bs4 import BeautifulSoup
from selenium import webdriver
driver = webdriver.Chrome(executable_path='C:/chromedriver')
url = 'https://shop.bodybuilding.com/search?q=protein bar&selected_tab=Products'
driver.get(url)
soup = BeautifulSoup(driver.page_source, 'html.parser')
all_items = soup.find_all('div', {'class': 'ProductTile ProductTile--flat Animate AnimateOnHover Animate--fade-in Animate--animated'})


for i in range(len(all_items)):
    prices=all_items[i].find('div', {'class': 'Price ProductTile__price'}).text
    names=all_items[i].find('p', {'class': 'ProductTile__title'}).text
    images=all_items[i].find('img')['src']
    url=all_items[i].find('a', {'class': 'Anchor ProductTile__image'})['href']

    print(images)

this is the result for the names on this page, as you see it only scrapes the first 4 elements !

BSN Protein Crisp Bars
Optimum Nutrition Protein Wafers
Herbaland Vegan Protein Gummies
Battle Bars Full Battle Rattle (FBR) Protein Bar

the same for prices, images, and URLs?

How to fix

You have to scroll, so all items will be loaded:

last_height = driver.execute_script("return document.body.scrollHeight")

while True:
    driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")

    time.sleep(1)

    new_height = driver.execute_script("return document.body.scrollHeight")
    if new_height == last_height:
        break
    last_height = new_height

soup = BeautifulSoup(driver.page_source, 'html.parser')
all_items = soup.find_all('div', {'class': 'ProductTile ProductTile--flat Animate AnimateOnHover Animate--fade-in Animate--animated'})


for i in all_items:
    prices=i.find('div', {'class': 'Price ProductTile__price'}).text if i.find('div', {'class': 'Price ProductTile__price'}) else None
    names=i.find('p', {'class': 'ProductTile__title'}).text
    images=i.find('img')['src']
    url=i.find('a', {'class': 'Anchor ProductTile__image'})['href']

    print(images)
