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 classic view.

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 has the following signature: customizeFunction(items: Array): 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 click on this item.
  • submenu (optional) – Array of objects. Array of 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 – Object. Information about the right-clicked object. In case of right click on the grid, this is a Cell Data Object containing information about the cell. In case of right click on the chart element, this is a Chart Data Object containing information about the chart segment.
• viewType – String. View type that was right-clicked. Can have one of the four possible values:
  1. "pivot" – Means that pivot grid was right-clicked, either compact or classic view.
  2. "flat" – Means that flat table view was right-clicked.
  3. "charts" – Means that charts view was right-clicked.
  4. "drillthrough" – Means that drill through view was right-clicked.

The customizeFunction function 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.
