d3-context-menu
Advanced tools
A plugin for d3.js that allows you to easily use context menus in your visualizations.
This is a plugin for d3.js that allows you to easy use context-menus in your visualizations. It's 100% d3 based and done in the "d3 way", so you don't need to worry about including additional frameworks.
It's written to be very light weight and customizable. You can see it in action here:
http://plnkr.co/edit/hAx36JQhb0RsvVn7TomS?p=info
bower install d3-context-menu
// Define your menu
var menu = [
{
title: 'Item #1',
action: function(d) {
console.log('Item #1 clicked!');
console.log('The data for this circle is: ' + d);
},
disabled: false // optional, defaults to false
},
{
title: 'Item #2',
action: function(d) {
console.log('You have clicked the second item!');
console.log('The data for this circle is: ' + d);
}
}
]
var data = [1, 2, 3];
var g = d3.select('body').append('svg')
.attr('width', 200)
.attr('height', 400)
.append('g');
g.selectAll('circles')
.data(data)
.enter()
.append('circle')
.attr('r', 30)
.attr('fill', 'steelblue')
.attr('cx', function(d) {
return 100;
})
.attr('cy', function(d) {
return d * 100;
})
.on('contextmenu', d3.contextMenu(menu)); // attach menu to element
});
Menus can have Headers and Dividers. To specify a header simply don't define an "action" property. To specify a divider, simply add a "divider: true" property to the menu item, and it'll be considered a divider. Example menu definition:
var menu = [
{
title: 'Header',
},
{
title: 'Normal item',
action: function() {}
},
{
divider: true
},
{
title: 'Last item',
action: function() {}
}
];
Menus can have Nested Menu. To specify a nested menu, simply add "children" property. Children has item of array.
var menu = [
{
title: 'Parent',
children: [
{
title: 'Child',
children: [
{
// header
title: 'Grand-Child1'
},
{
// normal
title: 'Grand-Child2',
action: function() {}
},
{
// divider
divider: true
},
{
// disable
title: 'Grand-Child3',
action: function() {}
}
]
}
]
},
];
See the index.htm file in the example folder to see this in action.
You can pass in a callback that will be executed before the context menu appears. This can be useful if you need something to close tooltips or perform some other task before the menu appears:
...
.on('contextmenu', d3.contextMenu(menu, function() {
console.log('Quick! Before the menu appears!');
})); // attach menu to element
You can pass in a callback that will be executed after the context menu appears using the onClose option:
...
.on('contextmenu', d3.contextMenu(menu, {
onOpen: function() {
console.log('Quick! Before the menu appears!');
},
onClose: function() {
console.log('Menu has been closed.');
}
})); // attach menu to element
You can use information from your context in menu names, simply specify a function for title which returns a string:
var menu = [
{
title: function(d) {
return 'Delete circle '+d.circleName;
},
action: function(d) {
// delete it
}
},
{
title: function(d) {
return 'Item 2';
},
action: function(d) {
// do nothing interesting
}
}
];
// Menu shown is:
[Delete Circle MyCircle]
[Item 2]
You can also have different lists of menu items for different nodes if menu is a function:
var menu = function(data) {
if (data.x > 100) {
return [{
title: 'Item #1',
action: function(d) {
console.log('Item #1 clicked!');
console.log('The data for this circle is: ' + d);
}
}];
} else {
return [{
title: 'Item #1',
action: function(d) {
console.log('Item #1 clicked!');
console.log('The data for this circle is: ' + d);
}
}, {
title: 'Item #2',
action: function(d) {
console.log('Item #2 clicked!');
console.log('The data for this circle is: ' + d);
}
}];
}
};
// Menu shown for nodes with x < 100 contains 1 item, while other nodes have 2 menu items

Default position can be overwritten by providing a position option (either object or function returning an object):
...
.on('contextmenu', d3.contextMenu(menu, {
onOpen: function() {
...
},
onClose: function() {
...
},
position: {
top: 100,
left: 200
}
})); // attach menu to element
or
...
.on('contextmenu', d3.contextMenu(menu, {
onOpen: function() {
...
},
onClose: function() {
...
},
position: function(d) {
var elm = this;
var bounds = elm.getBoundingClientRect();
// eg. align bottom-left
return {
top: bounds.top + bounds.height,
left: bounds.left
}
}
})); // attach menu to element
d3.contextMenu(menu, {
...
theme: 'my-awesome-theme'
});
or
d3.contextMenu(menu, {
...
theme: function () {
if (foo) {
return 'my-foo-theme';
}
else {
return 'my-awesome-theme';
}
}
});
d3.contextMenu('close');

Depending on the D3 library version used the callback functions can provide an additional argument:
var menu = [
{
title: 'Item #1',
action: function(d, event) {
console.log('Item #1 clicked!');
console.log('The data for this circle is: ' + d);
console.log('The event is: ' + event);
}
}
]
var menu = [
{
title: 'Item #1',
action: function(d, index) {
console.log('Item #1 clicked!');
console.log('The data for this circle is: ' + d);
console.log('The index is: ' + index);
}
}
]
