Description copied from corresponding location in WebComponent:

<vaadin-context-menu> <template> <vaadin-list-box> <vaadin-item>First menu item</vaadin-item> <vaadin-item>Second menu item</vaadin-item> </vaadin-list-box> </template> </vaadin-context-menu>

“vaadin-contextmenu” Gesture Event

vaadin-contextmenu is a gesture event (a custom event fired by Polymer), which is dispatched after either contextmenu and long touch events. This enables support for both mouse and touch environments in a uniform way.

<vaadin-context-menu> opens the menu overlay on the vaadin-contextmenu event by default.

Menu Listener

By default, the <vaadin-context-menu> element listens for the menu opening event on itself. In order to have a context menu on your content, wrap your content with the <vaadin-context-menu> element, and add a template element with a menu. Example:

<vaadin-context-menu> <template> <vaadin-list-box> <vaadin-item>First menu item</vaadin-item> <vaadin-item>Second menu item</vaadin-item> </vaadin-list-box> </template>

<p>This paragraph has the context menu provided in the above template.</p> <p>Another paragraph with the context menu.</p> </vaadin-context-menu>

In case if you do not want to wrap the page content, you can listen for events on an element outside the <vaadin-context-menu> by setting the listenOn property:

<vaadin-context-menu id="customListener"> <template> <vaadin-list-box> ... </vaadin-list-box> </template> </vaadin-context-menu>

<div id="menuListener">The element that listens for the context menu.</div>

<script> const contextMenu = document.querySelector('vaadin-context-menu#customListener'); contextMenu.listenOn = document.querySelector('#menuListener'); </script>

Filtering Menu Targets

By default, the listener element and all its descendants open the context menu. You can filter the menu targets to a smaller set of elements inside the listener element by setting the selector property.

In the following example, only the elements matching .has-menu will open the context menu:

<vaadin-context-menu selector=".has-menu"> <template> <vaadin-list-box> ... </vaadin-list-box> </template>

<p class="has-menu">This paragraph opens the context menu</p> <p>This paragraph does not open the context menu</p> </vaadin-context-menu>

Menu Context

You can bind to the following properties in the menu template:
- target is the menu opening event target, which is the element that the user has called the context menu for
- detail is the menu opening event detail
In the following example, the menu item text is composed with the contents of the element that opened the menu:

<vaadin-context-menu selector="li"> <template> <vaadin-list-box> <vaadin-item>The menu target: [[target.textContent]]</vaadin-item> </vaadin-list-box> </template>

<ul> <li>Foo</li> <li>Bar</li> <li>Baz</li> </ul> </vaadin-context-menu>
