Customizing Business Data List web part to toggle item details

Hi Experts,

I want to toggle item details in the Business Data List WP the way we can do it OOB in RSS Viewer WP.

As shown below, the item when unexpanded shows only the Topic field.

On clicking the link, it shows details.

I want to implement same toggling functionality in Business Data List WP. I have customized the XSLT to show just 2 fields without any headers.

Want some help toggling it in XSLT.

Please suggest.
