While we don’t prevent st.html components from calling Element.requestFullscreen() (which you can read more about here), we also don’t automatically add a fullscreen button overlay on the st.html component.
As a result, to have a fullscreen option display, you would need to do the following:
If you want a button to appear to allow users to select the fullscreen option, you’d need to implement it with HTML + JS in the code passed to st.html.
Thanks Caroline. I have not had a chance yet to try and implementation but I will look into it. I imagine with pydeck specifically it would require injecting in relevant code to replace the output to HTML pydeck generates.
