How to insert elements out of order?

You can use the st.empty method as a placeholder, to "save" a slot in your app that you can use later.

st.text('This will appear first') # Appends some text to the app. my_slot1 = st.empty() # Appends an empty slot to the app. We'll use this later. my_slot2 = st.empty() # Appends another empty slot. st.text('This will appear last') # Appends some more text to the app. my_slot1.text('This will appear second') # Replaces the first empty slot with a text string. my_slot2.line_chart(np.random.randn(20, 2)) # Replaces the second empty slot with a chart.
