Ag-Grid component with input support

Hi, Is there anyway to display the full contents of a cell in Ag-Grid when we click on it. My cell contents are too big. Resizing the columns of the table will make it less convenient for the user.

I’m looking for something like the second picture(normal st.dataframe). Displaying full cell contents when clicking on it

Ag-Grid table

Thanks! :slight_smile:

Hey Kiran, I have a couple ideas for hacks for this.

The closest thing to what you are looking for is probably the onCellClicked grid option. This option can take some JsCode that will be executed whenever a cell is clicked. I don’t know javascript well enough to tell you what that code should be, though. Using the GridOptionBuilder, this would look something like:
gb.configure_grid_options( onCellClicked = JsCode(“”“function(event) { <your code> }”“”) )

The second idea would be to mess with the master-detail stuff. The aggrid documentation for this is here. To use this for st_aggrid, you can use the gridOptionBuilder to set the option masterDetail to True, and set detailCellRendererParams to a dictionary which at least includes “getDetailRowData” : <Some JSCode to access the text>.

This may look something like:
“detailGridOptions”: {
“columnDefs”: <your code>,
“getDetailRowData”: JsCode(“”“function(params){

Not sure if that is exactly right because VulnerabilityImpact column has just strings instead of its JSON objects, but you can probably figure it out from there.

Finally, I think there might be grid options that works like onCellClicked but for double click and right click, but I don’t remember their names or how they work.

Thank you all for this! Just wondering, is grouping and hovering enabled from this package?

Hi @crsca, you can try out my sample code for grouping as below, and modify it for your use thereafter:

import pandas as pd
import streamlit as st
from st_aggrid import JsCode, AgGrid, GridOptionsBuilder
from st_aggrid.shared import GridUpdateMode

df=pd.DataFrame({ "Name": ['Paul', 'Gina'], "Age": [43, 35], "Inducted": [True, False], 
                  "Firm": ['Google', 'Microsoft'], "JDesc": ['Analyst', 'Programmer']})
gridOptions = GridOptionsBuilder.from_dataframe(df)
gb =

gb['columnDefs'] = [ { 'headerName': 'Personal Dtls', 'children': [ { 'field': 'Name' }, { 'field': 'Age' } ] }, 
                     { 'headerName': 'Partially', 'children': [{'field': 'Inducted'}] }, 
                     { 'headerName': 'Profession Dtls', 'children': [ { 'field': 'Firm' }, { 'field': 'JDesc' } ] }, 
                     { 'children': [{'field': 'Processed'}] } ]
dta = AgGrid(df, gridOptions=gb, height=350, theme="blue", update_mode=GridUpdateMode.SELECTION_CHANGED)

@Shawn_Pereira this worked perfectly! Thank you!

Just a quick follow up, how would you center the header names and is it possible to customize their background color?

I tried adding headerClass and cellClass, and still no luck.

gb[“columnDefs”] = [
“headerName”: “Personal Dtls”,
“headerClass”: “ag-center-header”,
“cellClass”: “ag-center-cell”,
“children”: [{“field”: “Name”}, {“field”: “Age”}],
{“headerName”: “Partially”, “children”: [{“field”: “Inducted”}]},
“headerName”: “Profession Dtls”,
“children”: [{“field”: “Firm”}, {“field”: “JDesc”}],
{“children”: [{“field”: “Processed”}]},

Hi @crsca, colours seem possible, but I didn’t get the time to try it out. Will let you know if that happens.


Hi @Shawn_Pereira,

Following this interesting post, do you know if it’s possible to add a onCellClicked grid event that enlarge the image in a popup window ? The goal would be to click on a cell and expand the image like this.

Thank you in advance for your response,
Best regards,


Hi @Louis_Monier, pls refer the code below for an implementation of onCellClicked. You could probably write the image into the new window (myWin) and expand it with JS. I didn’t get a chance to try it as yet. Do give it a shot at your end on the basis of the following code.

Hi @Kiran_K, below is an implementation of a browser window (instead of a popup). You can easily modify the JS to further suit your purpose.

Clicking on the Name field gives a standard JS popup; clicking on the Topics field gives a browser-based popup. I have inserted paragraph tags in the 3rd topic to illustrate line breaks. You can change the text attributes in the secondary browser window as required.

Copy & paste the code to test it out, and then repurpose it for your needs.

import pandas as pd
import streamlit as st
from st_aggrid import JsCode, AgGrid, GridOptionsBuilder
from st_aggrid.shared import GridUpdateMode

             update_mode=GridUpdateMode.SELECTION_CHANGED & GridUpdateMode.MODEL_CHANGED)




Awesome, it worked! I have applied this to the entire table using the below code.

def clicked_cell_func(col_name):
    return f"function(params){{ alert({col_name}); }};"

for col_index, col_name in enumerate(df.columns):
    gd.configure_column(f"{col_name}", headerTooltip="Click to sort data",
                        onCellDoubleClicked=JsCode(clicked_cell_func(col_name)), maxWidth=800)

I would like to add a row filled with the same values as the previous row. Can you help me to do that? Thanks :pray:


Have you found a solution for this? I am looking for the exact same but could not figure a way out yet.

Thanks in advance!

Hi @robert.k and @Joao_Alves

Here’s the sample code to insert a new row in Aggrid and set it to the previous row.

import pandas as pd
import streamlit as st
from st_aggrid import JsCode, AgGrid, GridOptionsBuilder
from st_aggrid.shared import GridUpdateMode

df=pd.DataFrame({ "Name": ['Erica', 'Rogers', 'Malcolm', 'Barrett'], "Age": [43, 35, 57, 29]})

add_row_func = """function(e) 
                    { let api = e.api; 
                      let rowIndex = e.rowIndex + 1; 
                      let vnme =;
                      let vage =;

                      api.applyTransaction({addIndex: rowIndex, add: [{'Name': vnme, 'Age': vage}]}); 

ShowAddBtn = JsCode("function addBtn(params) { return '<button style=background-color:green;>+</button>'; }")

gridOptions = GridOptionsBuilder.from_dataframe(df)
gridOptions.configure_column('+', headerTooltip='Add new row', editable=False, filter=False, 
                            onCellClicked=JsCode(add_row_func), cellRenderer=ShowAddBtn,

Thanks for the code @Shawn_Pereira!

My question would be, if anybody already found a solution to add a new row after clicking on a separate button? So instead of having an own column that has “add” in each row I am looking for a single st.button that would take over the task and add a new row.

Do you have any ideas?

Your help is much appreciated, thanks in advance!

Thanks a lot @Shawn_Pereira !
It’s not exactly what I wanted (modal popup that enlarges the image). But my friend chatGPT and I found a solution eventually !

Hi @robert.k , do you mean something like:

import pandas as pd
import streamlit as st
from st_aggrid import JsCode, AgGrid, GridOptionsBuilder
from st_aggrid.shared import GridUpdateMode

if "df" not in st.session_state:
    st.session_state.df = pd.DataFrame()

if st.session_state.df.shape[0] == 0:
  st.session_state.df=pd.DataFrame({ "Name": ['Erica', 'Rogers', 'Malcolm', 'Barrett'], "Age": [43, 35, 57, 29]})
gridOptions = GridOptionsBuilder.from_dataframe(st.session_state.df)
gb =

if st.button("Add New Row"):
  st.session_state.df.loc[len(st.session_state.df)] = ['', 0]

dta = AgGrid(st.session_state.df, gridOptions=gb, height=250, allow_unsafe_jscode=True, theme="blue",

Thanks for this component @PablocFonseca I am using it here App for searching the arxiv & it checks for valid Github links! - #14 by robmarkcole

When grouping and aggregating, i lose the formatting of the aggregated amount. Any assistance is appreciated.


Here is a snapshot of my code:
gb = GridOptionsBuilder()
gb.configure_column(“date”, type=[“dateColumnFilter”,“customDateTimeFormat”],
custom_format_string=‘MM-yyyy’, rowGroup=True, hide=True, sort=‘desc’)
gb.configure_column(“amount”, type=[“numericColumn”,“numberColumnFilter”,“customNumericFormat”],
valueFormatter=“data.AuctionAmt.toLocaleString(‘en-US’);”, precision=0, pivot=True, aggFunc=“sum”,

gb.configure_grid_options(groupDisplayType=‘multipleColumn’, suppressAggFuncInHeader=True)

#gb.configure_default_column(enablePivot=True, groupable=True, value=True, enableRowGroup=True, aggFunc=“sum”, editable=False)
gridOptions =

AgGrid(data[[‘date’, ‘amount’]],
gridOptions=gridOptions, enable_enterprise_modules=True, allow_unsafe_jscode=True)

this is what I want, thank you!
