Using ngContextMenu
you can easily support custom context menus for your application! Custom context menus are somewhat underused, but applications such as Gmail use them wisely to provide a richer UX.
First and foremost, you must add the script in your index.html and add the dependency to your module:
var app = $angular.module('menuApp', ['ngContextMenu']);
Then, you must create your context menu, which should be placed into your application as a separate file – a partial.
<ul class="menu">
<li>Read Message</li>
<li>Reply to {{from}}</li>
<li>Delete Message</li>
</ul>
Once you have the partial configured you can hook up the ngContextMenu
directive using the data-context-menu
attribute – passing along the path to your previously crafted partial. You may also supply an optional ngModel
which will be used to evaluate the template – otherwise it will be evaluated against an empty object ({})
.
<li data-context-menu="context-menus/message.html" ng-model="message"></li>
Before you begin to test the context menu, you must ensure that your context menu is positioned absolutely, since ngContextMenu
will apply the top
and left
properties to the node which will ensure it's opened where the cursor invoked the opening of the menu.
ul.menu {
position: absolute;
}
Now when you test your newly setup context menu, a right click on the node with the data-context-menu
attribute will open the context menu. Voila!
ngContextMenu
ships with a simple contextMenu
service which creates the necessary relationship between all of the context menus – this allows the opening of another menu —or a click on the document
node— to close the currently opened menu.
Sometimes you may wish to invoke this behaviour yourself, in which case you need to add the contextMenu
service to your controller, directive, service, and then invoke the cancelAll
method on it.
In some circumstances you may wish to add a controller for each context menu, in these cases it is preferrable to add the ng-controller
attribute to the element that also has the data-context-menu
attribute:
<li class="message" ng-controller="MessageController as mc" data-context-menu="context-menus/message.html">
/* ... */
</li>
