Drilldown diagram in HTML document

[IritP]

Hello,

In my project I have a class diagram that holds a fragment of another class diagram so I can open the second diagram from the first.
I use fragment (I choose Diagram Reference when dragging the second diagram) because I want to link that diagram to specific class.
In the HTML document that I generated, when I clicked the fragment I get the fragment element and not the relevant diagram I want to get.
I try to change the web style template but I can't find which HTML responsible of generating the diagrams.
Could sombody help me with this issue?

Regards,
Irit
