Bootstrap Context Menu

This project is a fork of https://github.com/sydcanem/bootstrap-contextmenu

This project is unmaintained but I prefer it to its alternative, jQuery-contextMenu, due to its light weight.

I've forked it mainly to publish it to npm, as I'm a fan of webpack. I will accept contributions and pull requests, issues, or even transfer the right to the project or the npm registry to someone more motivated than I am.

A context menu extension of Bootstrap made for everyone's convenience.

See a [demo page] id.

Installation

npm install bootstrap-contextmenu

Note: Requires bootstrap.css

Usage

Via data attributes

Add data-toggle="context" to any element that needs a custom context menu and via CSS set position: relative to the element.

Point data-target attribute to your custom context menu.

<div class="context" data-toggle="context" data-target="#context-menu"></div>

Via Javascript

Call the context menu via JavaScript:

$('.context').contextmenu({
  target:'#context-menu', 
  before: function(e,context) {
    // execute code before context menu if shown
  },
  onItem: function(context,e) {
    // execute on menu item selection
  }
})

Options

target - is the equivalent of the data-target attribute. It identifies the html of the menu that will be displayed.

before - is a function that is called before the context menu is displayed. If this function returns false, the context menu will not be displayed. It is passed two parameters,

• e - the original event. (You can do an e.preventDefault() to cancel the browser event).
• context - the DOM element where right click occured.

onItem - is a function that is called when a menu item is clicked. Useful when you want to execute a specific function when an item is clicked. It is passed two parameters,

• context - the DOM element where right click occured.
• e - the click event of the menu item, $(e.target) is the item element.

scopes - DOM selector for dynamically added context elements. See issue.

Events

All events are fired at the context's menu. Check out dropdown plugin for a complete description of events.

• show.bs.context - This event fires immediately when the menu is opened.
• shown.bs.context - This event is fired when the dropdown has been made visible to the user.
• hide.bs.context - This event is fired immediately when the hide instance method has been called.
• hidden.bs.context - This event is fired when the dropdown has finished being hidden from the user (will wait for CSS transitions, to complete).

Sample

$('#myMenu').on('show.bs.context',function () {
  // do something...
});

Example

Activate and specify selector for context menu

$('#main').contextmenu({'target':'#context-menu'});

Activate within a div, but not on spans

$('#main').contextmenu({
  target: '#context-menu2',
  before: function (e, element, target) {
      e.preventDefault();
      if (e.target.tagName == 'SPAN') {
          e.preventDefault();
          this.closemenu();
          return false;
      }
      return true;
  }
});

Modify the menu dynamically

$('#main').contextmenu({
  target: "#myMenu",
  before: function(e) { 
    this.getMenu().find("li").eq(2).find('a').html("This was dynamically changed");
  }
});

Show menu name on selection

$('#main').contextmenu({
  onItem: function(context, e) {
    alert($(e.target).text());
  }
});

Nice to have features:

• Close and open animations
• Keyboard shortcuts for menus
