Jumpy navigation bar fix

[alon-sht]

I found this very nice component
https://github.com/bouzidanas/streamlit-float/

Combining streamlit-float with the nav bar 'pinned' mode, makes it sticky and prevents it from being jumpy

Example:

import streamlit as st
import hydralit_components as hc
from streamlit_float import float_init

st.set_page_config(layout="wide")
menu_container = st.container()
with menu_container:
    menu= hc.nav_bar(
        [
            {"icon": "bi-info-circle-fill", "label": "Page 1"},
            {"icon": "bi-bar-chart-fill", "label": "Page 2"},
            {"icon": "bi-search", "label": "Page 3"},
        ],
        key="test_menu",
        sticky_mode="pinned",
    )
menu_container.float("top: 0.0rem; bottom:10rem ;z-index: 999990;")

it does require adding some blank space at the top, but it might be nice to integrate it into hc
