How can I increase the size of the multiselect placeholder?
I have placed several markdowns with JS and CSS but they have not given results. What I want is to increase the size of the letters inside the place holder, my code is:

import streamlit as st
import pandas as pd

df = pd.DataFrame({
    "LABEL": ["Label 1", "Label 2", "Label 3", "Label 4"]
})

lorem = st.sidebar.multiselect("Label", df["LABEL"].unique(), placeholder="Label selection", label_visibility='collapsed')


st.write("label:", lorem)

Thanks in advance for the help

Here’s one way to do it:

import streamlit as st
import pandas as pd

df = pd.DataFrame({
    "LABEL": ["Label 1", "Label 2", "Label 3", "Label 4"]
})

lorem = st.sidebar.multiselect("Label", df["LABEL"].unique(), placeholder="Label selection", label_visibility='collapsed', key="my_select")


st.write("label:", lorem)


CSS = """
.st-key-my_select .stMultiSelect>div>div>div>div>div{
    font-size: 2em;
}
"""

st.html(f"<style>{CSS}</style>")
