Using Streamlit

Sharing the answer from this thread here:

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:

  1. The code that you pass to st.html would need to make a call to the Element.requestFullscreen() API.
  2. 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.
