Yes, this ability is available through the OnMenuBarClick property on the Group object. This property allows you to execute client-side JavaScript from any MenuBar button click. The JavaScript code can be any type of supported action for the web browser, including loading a new page through the location.href property.

To open a new window:

$objGroup->setOnMenuBarClick("window.open('http://www.domain.com/page', 'WindowName');");

To target the current page:

$objGroup->setOnMenuBarClick("location.href = 'http://www.domain.com/page';");

To target a specific browser frame:

$objGroup->setOnMenuBarClick("top.{framename}.location.href = 'http://www.domain.com/page';");

Note that {framename} is the NAME attribute of the <FRAME> tag provided in the FRAMESET document that you created. This value may be case-sensitive.
