Hi! I am new to Python and Streamlit, so this might not make sense :slight_smile: . What I would like to do is, within a form, to get data from one input field and use it in another input field. I have the following code: full_date = date_input('Date:', datetime.date.today(), key='data_inv_key', h…

You can’t do that within a form.

I see, thanks. Then, can the user submit the form once a date is selected in the date_input field? Something equivalent to pressing Enter while in a text_input filed?

I dont think so. AFAIK only text_input and text_area have that kind of functionality.
