JavaScript Datagrid Grouping
Wijmo's JavaScript datagrid, FlexGrid, allows you to group data via CollectionView. Set multiple groups in a single datagrid and implement an Outlook-style GroupPanel to allow users to drag-and-drop columns to create groups.
Grouping
Group rows around a column value in FlexGrid to display the data in an organized, hierarchical structure in JavaScript applications.
Drag-and-Drop Grouping
Implement GroupPanel, an Outlook-style JavaScript grouping UI, with FlexGrid to allow users to manually create groups. It creates a panel that enables users to drag-and-drop columns onto–creating groupings in the datagrid based on the column's new location.
