We just added a list template that you can use for your plugin. :) You can learn more about it here: https://github.com/duckduckgo/duckduckgo-documentation/blob/master/duckduckhack/spice/spice_templates_overview.md#list

One plugin that uses the list template is the Github plugin. Take a look at https://duckduckgo.com/?q=github+zeroclickinfo to see how it looks. Here's the code that does the whole thing for us: https://github.com/duckduckgo/zeroclickinfo-spice/blob/master/share/spice/github/github.js#L16
