Overview

SpreadJS supports built-in context menus, the context menu can be opened by right-clicking on the SpreadJS instance. The contents of this menu depend on which area of the workbook is clicked.

<p>The context menu provides the following abilities:</p> <ul> <li><strong>Theme is the same as the current spread theme.</strong></li> <li><strong>Change the filter context menu data result.</strong></li> <li><strong>Modify the menu view's appearance and structure.</strong></li> </ul> <p>You can use the <strong>spread.options.allowContextMenu</strong> option to control whether to show the built-in context menu or not.</p> <pre><code class="hljs js language-js"> <span class="hljs-keyword">var</span> spread = GC.Spread.Sheets.findControl(<span class="hljs-built_in">document</span>.getElementById(<span class="hljs-string">'ss'</span>)); spread.options.allowContextMenu = <span class="hljs-literal">false</span>; </code></pre>
