What’s New in Ext JS 6.5.1

Ext JS 6.5.1 includes multiple enhancements to Grid, Tree Grid, Pivot Grid, tabs, toolbars, forms, date panel, and more. Below are the key changes to Ext JS components.


Ext JS Grid, along with the selectable config in Grid, now also support the Clipboard plugin. The Clipboard plugin supports multiple formats including html for rendered html tags, text, and raw for underlying field values based on dataindex and cell.

Sencha Ext JS 6.5.1 - Grid

Grids often need to show extra details that may not fit in a column’s cell or header. Now, you can configure an overflow tip. When a cell in a grid has more text than fits, it will show an ellipsis. When a user hovers over that cell, it will show a tooltip with the entire text.

Number field validations and modified cell renditions have been improved in the grid as well.

Tree Grid

The Tree component is closely related to Grid and shares many of its features such as Grid plugins for editing content. With Ext JS 6.5.1, you can use the “Exporter” plugin to export selected rows in the tree grid along with the header and summary row.

Tab Panels

Tab panels now support overflow scrolling, so your application can have multiple tabs that can be easily scrolled along with support for ripple and indicator animation. With overflow handler controls, you have complete control to enable or disable scrollbar visibility.

Pivot Grid

The Pivot Grid aggregator functions now provide options that behave more like Excel. Your data sets can include null values, and you have the option to ignore null values, just like in Excel, using the property calculateAsExcel. The count numbers function of Excel is supported in both the Configurator as well as Exporter plugins.

Date Panel

With Ext JS 6.5.1, we’ve made multiple styling improvements to the datepanel component including a rounded style for Selected date and Today’s date. There is also a UI mixin for datepanel that allows you to easily create custom themes.

What’s New in Sencha Cmd 6.5.1

Sencha Cmd 6.5.1 helps you to create optimal builds for large web applications. It includes the following key features:

Minimum Build for Dynamically Loaded Packages

In Ext JS 6.5.0, the build output for applications that used the new dynamic package loader included all framework classes. That was because the dynamically loaded packages were built separately and their framework dependencies were not known to the application.

With Ext JS 6.5.1, the class requirements of dynamic packages can be passed to the application build and allow it to include only those classes needed, as shown below:

    "output": {
        "js": {
            "filter": "minimum"   

Manually Exclude Classes from Build

You can now manually exclude class names from the build. This is helpful for removing code that is detected by the Sencha Cmd auto dependency scanner, but is not actually used by your application. For example:

    "js": {
        "exclude": [
