How to expand ExtJS SplitB开发者_运维问答utton, to see sub items, from code?

Ext version 3.1.0

Thanks.

Try the showMenu() method to display the menu items.

sptButt.showMenu();

Hope this helps.

This is an example how to open context menu by clicking on a split button:

{
    xtype: 'splitbutton',
    text: 'This is a split button, no kidding',
    handler: function () {
        this.showMenu();
    }
}
