App with many pages but not all loaded at once

Stefano,
Thanks for your response.
I am using Python requests (see below) to open the url and download the html, then I examine the html and find that all ten pages have been downloaded, even though none of the menu items have been clicked yet.

import requests

def getWebPage(url):
headers = {‘User-Agent’: user_agent}
response = requests.get(url,headers=headers)
html = response.content
return html.decode()

url = ‘https://my-anvil-appliaction.anvil.app/
user_agent = ‘Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:102.0) Gecko/20100101 Firefox/102.0’

html = getWebPage(url)
