GOJS diagram and JQuery Color Picker Dialogbox

I need to build style setter component, where provided setting for changing color, opacity level etc.

For changing opacity level, provided slider control but it doesn’t look well in IE. So wants to build this component using diagram component.
To meet same, needs to provide one node when clicked, needs to display JQuery Color picker dialog box.

How this can be achieved ??

I assume you know about the GraphObject.click event handler or about the “ObjectSingleClicked” DiagramEvent listener. GoJS Events -- Northwoods Software

Please also understand the difference between clicking and selecting: GoJS Events -- Northwoods Software
