Hi there, Have been using Streamlit for a few weeks and am really loving it. I’ve built an app that performs 10-20s of computation, displaying output as it goes. Once it comes to the end, I would like it to ask the user if they want to see additional information. The idea is that this would be a …

Hi @Doggie52 , First, welcome to the Streamlit community! :tada: :hugs: :star: :partying_face: Although session state seems like it might not apply in this case it does. What you want to do is use the button to add or change a value that you hold in state, and you will use this value to display you…

Hi Marisa - thanks for getting back to me. Unfortunately, your example isn’t a solution to my problem - I took your code, added a spinner with a sleep to it at the top of the page and found that clicking the “Do you want to see more?” button did indeed re-trigger that spinner. The expander isn’t a …

Hi @Doggie52 , So, let me be clear, the Streamlit execution flow will always work like this. Each time you interact with a widget on the page the entire Streamlit script will be re-run from top to bottom. The button solution I provided allows you to “hide” additional widgets behind a button click. …

Thanks for getting back to me. As you indicate, I think it isn’t possible to work around this behaviour in Streamlit right now.

Hey @Doggie52 , you can probably solve this with caching . But could you give me a few more details about what you are doing in your app (i.e. the “10-20s of computation, displaying output as it goes”)? We are currently looking at how we can improve caching, so this would be really useful feedback f…

Hey there - apologies for a belated reply. Happy to jump on a call - love the product so am happy to offer any input. Will DM you!

Is there any solution for this issue now??

Re-running the application on each button click is pretty much unavoidable. If that is making your application slow, the solution is caching, either using cache primitives or session_state.

Well, this example worked for me: [image] St.multiselect with cache? CacheDataAPI.call() got an unexpected keyword argument ‘suppress_st_warning’ 🎈 Using Streamlit Hey @mabusdogma wave Sorry for the wait! Here’s the code rewritten to satisfy both those constraints: imp…

Hi! I’m also running into this exact same issue & would love help! I’m working on an app where a user inputs a prompt: the response dataframe is displayed, and I want them to be able to edit this dataframe response using st.dataeditor, and the edited dataframe is stored as a variable and then the …
