To make a streamlit apps, we may want
- use multiple pages(so we can have many functions without execute all codes etc.)
- change application urls for each page and selected fields
- so we can pass a url to guide users to a specific page
- so we can add links in the apps to guide user to another view(to recommendation of items in a recommendation list)
- pack pre-process together
- use a front(index) page
- etc.
this is a template to make these easily
implement a page class, write the code in a run method
add the page class to page_class in app.py
Source code changes in AppData and AppURL will not reflect until restart apps.
You cannot empty the field after select(only to reset to another value).
