Set_page_config function

[KhaledHassine11]

In a multi-page web app, we need to set the configuration for each page. Why we can use this function only on time in an app?

Hi @Khaled11111111,

The function is limited to one call per script run to prevent dynamic changes to the page layout which may confuse a user if it's not clear why, for example, the page layout switched from centered to wide mode.

Closing as this isn't a feature request/bug report/etc. I'd recommend posting these types of questions in our community forums in the future.

I'm a bit confused about this not being described as a feature request or bug report in multi-page apps. If the st.set_page_config is called on the main page and the preference is for layout='wide', then all pages inherit this layout. Great.

However, if you have the app open in a browser on one of the pages (not main), then you go to another tab, do something else, then come back, the layout has changed. This is because of the browser behaviour with tabs, I think, in that it calls for a refresh on idle tabs when revisited. So the page itself does not have the st.set_page_config call, and the view goes awry.

One solution would be to allow layout to be set in the config.toml file maybe?

In any case, I'd be keen to hear what the solution is.

Agree with "all pages inherit this layout". Any updates?

Any updates on this? I'm still having trouble with st.set_page_config for multipages
