@shashankdeshpande, as far as I understood, it's not a bug. The thing is, you used two TABS in the markdown list, so the parser interprets them as nested elements of a list. Just remove one tab, and it should work:

import streamlit as st
with st.expander('Expand this', expanded=True):
    st.markdown('''
        List of items
    - item 1
    - item 2
    - item 3
    ''')

@antonace Thanks for suggestion! Tried removing tab but it's not working. I guess this is a bug as we are not getting same view for same markdown text.

Code snippet:

import streamlit as st
default_val = '''
List of items
- item 1
- item 2
- item 3
'''
markdown_text = st.text_area('Enter markdown text', value=default_val)
col1, col2 = st.columns(2)
col1.markdown(markdown_text)
with col2.expander('Expand this', expanded=True):
    st.markdown(markdown_text)

Output:

Marking this as bug again. The example above actually doesn't work correctly, even though it should. Seems to be conncected to the expander.

Did some initial investigation, but it looks like the bug is a result of the fact that the expander is considered a ul and the list is a ul. So the marker is defined a s a sub-list. Seems like we need to manage this differently so the expander is not a ul
