1.1 mike 383: describing available commands.<p>The <dfn aria-haspopup="true" id="attr-menu-label" role="button" tabindex="0"><code>label</code></dfn>
384: attribute gives the label of the menu. It is used by user agents to
385: display nested menus in the UI. For example, a context menu
386: containing another menu would use the nested menu's <code title="attr-menu-label"><a href="#attr-menu-label" id="label_40">label</a></code> attribute for the submenu's
1.5 ! mike 387: menu label.<h5 id="menus-intro"><span class="secno">4.11.4.1 </span>Introduction</h5><p>The <code><a href="#the-menu-element" id="menu_18">menu</a></code> element is used to define context menus and
1.1 mike 388: toolbars.<p>For example, the following represents a toolbar with three menu
389: buttons on it, each of which has a dropdown menu with a series of
390: options:<pre><menu type="toolbar">
391: <li>
392: <menu label="File">
393: <button type="button" onclick="fnew()">New...</button>
394: <button type="button" onclick="fopen()">Open...</button>
395: <button type="button" onclick="fsave()">Save</button>
396: <button type="button" onclick="fsaveas()">Save as...</button>
397: </menu>
398: </li>
399: <li>
400: <menu label="Edit">
401: <button type="button" onclick="ecopy()">Copy</button>
402: <button type="button" onclick="ecut()">Cut</button>
403: <button type="button" onclick="epaste()">Paste</button>
404: </menu>
405: </li>
406: <li>
407: <menu label="Help">
408: <li><a href="help.html">Help</a></li>
409: <li><a href="about.html">About</a></li>
410: </menu>
411: </li>
412: </menu></pre><p>In a supporting user agent, this might look like this:<p><img alt="A toolbar with three buttons, labeled 'File', 'Edit', and 'Help'; where if you select the 'Edit' button you get a drop-down menu with three more options, 'Copy', 'Cut', and 'Paste'." height="101" src="http://dev.w3.org/html5/spec/images/sample-toolbar-1.png" width="303"><p>In a legacy user agent, the above would look like a bulleted list
413: with three items, the first of which has four buttons, the second of
414: which has three, and the third of which has two nested bullet points
415: with two items consisting of links.<hr><p>The following implements a similar toolbar, with a single button
416: whose values, when selected, redirect the user to Web sites.<pre><form action="redirect.cgi">
417: <menu type="toolbar">
418: <label for="goto">Go to...</label>
419: <menu label="Go">
420: <select id="goto">
421: <option value="" selected="selected"> Select site: </option>
422: <option value="http://www.apple.com/"> Apple </option>
423: <option value="http://www.mozilla.org/"> Mozilla </option>
424: <option value="http://www.opera.com/"> Opera </option>
425: </select>
426: <span><input type="submit" value="Go"></span>
427: </menu>
428: </menu>
429: </form></pre><p>The behavior in supporting user agents is similar to the example
430: above, but here the legacy behavior consists of a single
431: <code><a href="the-select-element.html#the-select-element" id="select_43">select</a></code> element with a submit button. The submit button
432: doesn't appear in the toolbar, because it is not a direct child of
1.5 ! mike 433: the <code><a href="#the-menu-element" id="menu_19">menu</a></code> element or of its <code><a href="the-li-element.html#the-li-element" id="li_17">li</a></code>
1.1 mike 434: children.<h5 id="context-menus"><span class="secno">4.11.4.2 </span><dfn aria-haspopup="true" role="button" tabindex="0">Context menus</dfn></h5><p>The <dfn aria-haspopup="true" id="attr-contextmenu" role="button" tabindex="0"><code>contextmenu</code></dfn>
435: attribute gives the element's <a href="#context-menus" id="context-menus_0" title="context menus">context
1.5 ! mike 436: menu</a>. The value must be the <a href="elements.html#concept-id" id="concept-id_21" title="concept-id">ID</a> of a <code><a href="#the-menu-element" id="menu_20">menu</a></code> element
1.1 mike 437: in the DOM. <div class="example">
438:
439: <p>Here is an example of a context menu for an input control:</p>
440:
441: <pre><form name="npc">
442: <label>Character name: <input name=char type=text contextmenu=namemenu required></label>
443: <menu type=context id=namemenu>
444: <command label="Pick random name" onclick="document.forms.npc.elements.char.value = getRandomName()">
445: <command label="Prefill other fields based on name" onclick="prefillFields(document.forms.npc.elements.char.value)">
446: </menu>
447: </form></pre>
448:
449: <p>This adds two items to the control's context menu, one called
450: "Pick random name", and one called "Prefill other fields based on
451: name". They invoke scripts that are not shown in the example
452: above.</p>
