Responsive Web Design

We can dynamically react to screen changes by making use of the grid API features. In this section we describe a few recommended approaches to resize the grid and show/hide columns based on screen size changes.

These recipes below are suggestions - as the grid can be placed & positioned in your application in many ways and with many frameworks the suggestions below may not work out of the box in your particular application, but they should serve to help point you in the right direction.

Dynamic Resizing with Horizontal Scroll

The quickest way to achieve a responsive grid is to set the grid's containing div to a percentage. With this simple change the grid will automatically resize based on the div size and columns that can't fit in the viewport will simply be hidden and available to the right via the scrollbar.

Dynamic Resizing without Horizontal Scroll

Sometimes you want to have columns that don't fit in the current viewport to simply be hidden altogether with no horizontal scrollbar.

To achieve this determine the width of the grid and work out how many columns could fit in that space, hiding any that don't fit, constantly updating based on the gridSizeChanged event firing:

// get the current grids width
var gridWidth = document.getElementById('myGrid').offsetWidth;

// keep track of which columns to hide/show
var columnsToShow = [];
var columnsToHide = [];

// iterate over all columns (visible or not) and work out
// now many columns can fit (based on their minWidth)
var totalColsWidth = 0;
var allColumns = gridOptions.columnApi.getAllColumns();
for (var i = 0; i < allColumns.length; i++) {
    let column = allColumns[i];
    totalColsWidth += column.getMinWidth();
    if(totalColsWidth > gridWidth) {
    } else {

// show/hide columns based on current grid width
gridOptions.columnApi.setColumnsVisible(columnsToShow, true);
gridOptions.columnApi.setColumnsVisible(columnsToHide, false);

// fill out any available space to ensure there are no gaps

This example is best seen when opened in a new tab - then change the horizontal size of the browser and watch as columns hide/show based on the current grid size.

Dynamic Vertical Resizing

Sometimes the vertical height of the grid is greater than the number of rows you have it in. You can dynamically set the row heights to fill the available height as follows:

// get the height of the grid body - this excludes the height of the headers
var gridHeight = document.getElementsByClassName('ag-body')[0].offsetHeight;

// get the rendered rows
var renderedRows = gridOptions.api.getRenderedNodes();

// if the rendered rows * min height is greater than available height, just just set the height
// to the min and let the scrollbar do its thing
if(renderedRows.length * minRowHeight >= gridHeight) {
    if(currentRowHeight !== minRowHeight) {
        currentRowHeight = minRowHeight;
} else {
    // set the height of the row to the grid height / number of rows available
    currentRowHeight = Math.floor(gridHeight / renderedRows.length);
    console.log(gridHeight + " / " + currentRowHeight);

This example is best seen when opened in a new tab - then change the horizontal size of the browser and watch as columns hide/show based on the current grid size.
