streamlit-custom-sidebar

Streamlit component that allows you to do buid a more flexible customizable sidebar that does not look buggy when rendered. Usually when we try to adjust the native streamlit sidebar it gets rendered after all the streamlit default settings are rendered. With this, your default settings are rendered when the page loads but it still uses streamlit's sidebar mative settings - css like its open and close animation and buttons.

Dependencies: Uses other custom components I created:

• local storage
• browser session storage
• streamlit-extras

Installation instructions

pip install streamlit-custom-sidebar

# Pre-requisites

create `.streamlit/config.toml` directory where the main app.py file is located

in there, input 
[client]
showSidebarNavigation = false

Usage instructions

import streamlit as st
from streamlit_custom_sidebar import CustomSidebarDefault
import streamlit_float # recommended

# Note - on the page's first load - when user comes in from the url rather than clicking on the tab, the active page will be derived from the url or from the `loadPageName` parameter. Please make sure all params in the data array object are inputed.

st.set_page_config(layout="wide")

streamlit_float.float_init(include_unstable_primary=False)

#if the rendering gets too buggy that you don't feel comfortable, a simple time.sleep(2) helps after this component.
time.sleep(2) # optional

data_ = [
            {"index":0, "label":"Example", "page":"example", "href":"http://localhost:8501/"},
            {"index":1, "label":"Page", "page":"page", "icon":"ri-logout-box-r-line", "href":"http://localhost:8501/page"}
        ]

if "currentPage" not in st.session_state: # required as component will be looking for this in session state to change page via `switch_page`
    st.session_state["currentPage"] = data_[0] 
else:
    st.session_state["currentPage"] = data_[0] 


with st.container():
    defaultSidebar = CustomSidebarDefault(closeNavOnLoad=False, backgroundColor="brown", loadPageName="example", data=data_, LocalOrSessionStorage=1, serverRendering=False, webMedium="local") 
    defaultSidebar.load_custom_sidebar()
    defaultSidebar.change_page()
    
    streamlit_float.float_parent(css="position:fixed; top:-1000px;") # gets rid of the whitespace created from the iframes used to build the component - no big forehead.

# The above must be rendered atop every streamlit page
