How to draw a line between Zk components? Not just a horizontal line but a zig-zag line.
Basically, I have a hyperlink that I need to connect to a small window. And it is not one instance on the same page there could be more than 10 such connectors. Each connector, connects the link to a discussion window.

Any idea is greatly appreciated.

If you want draw a zig-zag line, you should calculate and draw by yourself, there's not any easy way to draw it now.
And there's a suggestion for your case(show window for different connectors), apply a Composer to control the zul page,
use Executions.createComponent() to decide when and how to show the window. If all the connectors will do things in the
same window, you could use Server-Push or script to auto-refresh the window, make sure all users will see the same data.

Reference:
ZK Composer
ZK-API Executions.createComponent()
Server-Push

Thanks so much for your reply.
However, the key part for me is how to draw a line in ZK. I can figure out how to calculate the points but how do I connect the two points is the question.

Any pointers in this regard will be greatly appreciated.

Have you tried the separator component?

Thanks so much for all the info.

Canvas looks promising, I am going to see how it can help me.

I have used the seperator for spacing only, is there something else that it does?

<separator bar="true" /> shows a line. Additionally you can set the lines orientation to vertical or horizontal.
