customizeContextMenu

customizeContextMenu(customizeFunction: Function)

[starting from version: 2.6]

This API call allows customizing the context menu. For example, you can create a context menu for a flat table or remove all context menu items for the classic view. Learn more in this guide: Customizing the context menu.

customizeContextMenu can be defined in two ways:

1. As a regular API call: flexmonster.customizeContextMenu(customizeFunction: Function).
2. As an initialization parameter: new Flexmonster({customizeContextMenu: customizeFunction, ...}).

Parameters

• customizeFunction – Function. It has the following signature: customizeFunction(items: Array, data: CellDataObject | ChartDataObject, viewType: String): Array.
  Data passed to the customizeFunction:
  • items – Array of objects. Context menu items created by Flexmonster. Each object can have the following properties:
    • id – String. The ID of the menu item.
    • label – String. The name of the menu item.
    • handler – Function. The function that handles clicks on this item.
    • submenu optional – Array of objects. Contains submenu items. Each submenu item has the same structure as items.
    • isSelected optional – Boolean. Specifies whether the menu item is selected.
    • class optional – String. Adds a custom CSS class to the specified item.
  • data – CellDataObject | ChartDataObject. Information about the right-clicked object. In the case of right-clicking on the grid, this is a CellDataObject containing information about the cell. In the case of right-clicking on the chart element, this is a ChartDataObject containing information about the chart segment.
  • viewType – String. View type that was right-clicked. Can have one of the four possible values:
    • "pivot" – Means that the pivot grid was right-clicked, either compact or classic view.
    • "flat" – Means that the flat table view was right-clicked.
    • "charts" – Means that the chart view was right-clicked.
    • "drillthrough" – Means that drill through view was right-clicked.
  The customizeFunction must return items, the array of new or changed context menu items. If items is null, the default items will be used. If items is [], the context menu will be hidden.

Examples

1) Add a “Switch to charts” option to the flat table context menu:

flexmonster.customizeContextMenu(function(items, data, viewType) {
	if (viewType == "flat") 
		items.push({
			label: "Switch to charts",
			handler: function() {
				flexmonster.showCharts();
			}
		});
	return items;
});

Open the example on JSFiddle.

2) Remove “Aggregation” item from all the context menus:

flexmonster.customizeContextMenu(function(items, data, viewType) {
	items = items.filter(function (item){
				return item.label !== "Aggregation"
			})
	return items;
});

Open the example on JSFiddle.
