Creating a BSP for ESS Benefits enrollment

Friends,

I am new to BSP, I have a task where i got to display all the benefits plans available to an employee on the left hand side of the web page or so called navigation area. When the user clicks on the nodes in the left hand side, his relevant information regarding that particular benefit plan should be displayed on the right hand side of the web page. I want to know what is the best way to start off designing it with BSP.

I figured out html element Tree to dynamically fill in the navigation area from an internal table.

but the problem for me is how to display the relevant content on the right side of the page dynamically when a node is clicked in the same pages navigation area.

Please reply me as soon as possible.

Thanks,

Linda
