Context Menus
Grid has a context menu, which can be used for various editing functions. The context menu uses the standard Vaadin action handler mechanism.
Default Context Menu
The SpreadsheetDefaultActionHandler provides a ready set of common spreadsheet editing operations.
Add, delete, hide, and show rows and columns
Insert, edit, and delete cell comments
Merge and unmerge cells
Add filter table to selected range
The default context menu is not enabled by default; to enable it, you need to create and set it as the action handler explicitly.
sheet.addActionHandler(new SpreadsheetDefaultActionHandler());
Custom Context Menus
You can implement custom context menus either by implementing an ActionHandler or extending the SpreadsheetDefaultActionHandler. The source code of the default handler should serve as a good example of implementing context menu items for different purposes.
