Date Pickers

Smoothened animations

The animations have been smoothened, especially on Android devices, ensuring a more fluid user experience.

Clearable Field

A much-anticipated feature, the date and time fields now allow users to clear a selected date with a single click. You can learn how to use it at the clearable behavior documentation.

Customization Playgrounds

We're constantly improving our documentation and working to better communicate how to use our components effectively. With the new customization playgrounds, you can now tailor the style of Date Picker and experiment with multiple combinations of sub-components to achieve the look and feel you desire.

Data Grid

Column Autosizing

The new autosizing feature automatically adjusts the column width to accommodate the content within. You can include or exclude both headers and outliers from the calculation and expand to use the entire area of the grid. Learn more details at column autosizing section.

New examples

We're continuously improving our docs, and we're starting to add more advanced examples like bulk editing and lazy loading for tree data.

Sparkline as a column type

Based on @mui/x-charts package, you can now add sparkline columns to your Data Grid.

Performance improvements

In our pursuit to enhance user experience, one of the most significant changes in latest v6 versions are related to performance boosts on filtering and scrolling.

To illustrate some of these improvements, the following table display a benchmark comparing the latest v5 (v5.17.26) with v6.18.0. The focus is to assess the raw filtering speed in a use case involving a one-column string filter over 100,000 rows.

Version N# of Tests Min time (ms) Max time (ms) Median (ms) Average (ms) Deviation
v5.17.26 22 396 409 400.0 400.7 3.96
v6.18.0 20 44 66 49.5 50.4 5.63

As we can see, the current version operates 7.9 times faster; the average time has dropped from 400.7 milliseconds in the previous version to just 50.4 milliseconds in the current one.

What's next?

We're now working on the next MUI X major, v7, which will include many new features and improvements.

Most notably:

  • DateTime and TimeRangePicker
  • Improved accessibility on date and time fields
  • New UI for column management for the DataGrid
  • Pivoting for the DataGridPremium

For the new components, we will keep expanding our portfolio with new chart types such as Heat map, Funnel, Gantt, and explore virtualization and other advanced use cases for Tree view.

We encourage you to upvote issues on GitHub to help us prioritize. Your input directly influences our development schedule, so don't hesitate to let us know what matters most to you! You can use the following list for quick access to each components issues.

The next major release (v7) will be available through alpha and beta versions until March 2024, when it's planned for it to be officially promoted to the new stable version. At the same time, v6 will transition to Long-Term Support, while support for v5 will be discontinued.
