Summary
I found that enter to submit only works for text entry elements - it doesn't work for:
- radio selections
- dataframe selections
- number inputs
- presumably others (selectbox etc.)
Why?
When I test my own forms, which rely on the st.dataframe row selection feature, intuitively I select and press Enter (Return) and expect the form to submit.
Limiting this only to text reduces the usefulness of forms, quite a lot for me
How?
however the text input works -- repeat for all input elements!
Squeezing in the 'Enter to submit' message probably isn't possible, but that's okay.
Additional Context
import streamlit as st
import pandas as pd
test_number = 0
with st.form(key='form_select_step',enter_to_submit=True):
a1,a2,a3,a4 = st.columns([25,25,25,25])
test_radio = a1.radio('radio',['test1','test2','test3'],index=0)
test_dataframe = pd.DataFrame({'test':[1,2,3]})
a2.write('dataframe')
test_dataframe_selection = a2.dataframe(test_dataframe,on_select='rerun',selection_mode='single-row')
test_number = a3.number_input('number',value=10)
test_string = a4.text_input('string',value='test')
st.form_submit_button('form submit')
a1,a2,a3,a4 = st.columns([25,25,25,25])
a1.write('Test Radio:')
a1.write(test_radio)
a2.write('Test Dataframe Selection:')
a2.write(test_dataframe_selection)
a3.write('Test Number:')
a3.write(test_number)
a4.write('Test String:')
a4.write(test_string)

Hey, it does work for st.number_input. I can see the point of having it work for other elements as well but they are definitely a bit less obvious UX since you don't really have a cursor/input field there.
