I’m using the st.sidebar functionality to split my app up into pages. Within a given page, the states of any interactive widgets are preserved (e.g., text entered into a st.text_input field) even if I navigate to a different page and then come back later. However, variables/states that are set on on…

Good point. You can address that by setting the widget default to the state value: session_state.a = float(st.text_input(label="What is a?", value=session_state.a)) I’ll update the post above and the Gist. Thanks! Edit: hmm… I’m experiencing a small bug in the script above, where the first time …

Very cool, I was looking for something like this. Instead of (or in addition to) having get create a SessionState, could you consider allowing the user to create a Dataclass as state so the code complete in the editor is more helpful? From what I can tell SessionState is just a regular object so it …

Hi @zabzug I’m also creating a multiapp and i’m very interested in how to do it. Feel free to share your experiences, study the awesome-streamlit app or reach out. How do you structure your navigation? I use the radiobuttons as there is currently no menu. Can I see your multipage app somewhere? S…

Hi Marc, My app is structured very similarly to yours, I’m just using a “selectbox” (dropdown menu) instead of radio buttons. Unfortunately, I can’t share the app since I built it for my job. But yours looks great, keep up the good work! Zack

@biells: This is a great idea. We’re considering this!

Edit: hmm… I’m experiencing a small bug in the script above, where the first time you edit one of those text boxes the UI resets to 0 but the session state is set correctly. I’ll look into this later today. I really like @thiago ’s gist for session state, but I’m experiencing this same bug and I…

Is there a solution for this? My usecase is the following: load a df be able to preprocess that df, save the state into a new df (the preprocessed data) visualize the preprocessed data run a model with the preprocessed data and save the results into a df visualize the model results in page == ‘Vis…

I am using the “multi-select” widget within the sidebar and running into the same issue (even when attempting to use the SessionState work around). Each time the code runs the “multi-select” widget presents the default options in the sidebar even though that may not be the data presented on the sc…

any more updates from anyone on this issue?
