I assume you have read the help page for portable infoboxes?

Regarding tabs, there are 3 options:
 * 1) Tabber - I was under the impression that this breaks the portability of the infobox but someone else told me otherwise recently. So I am not sure what the deal is with using Tabber in a portable infobox.
 * 2) Panel and Section - This is essentially the infobox version of Tabber.
 * 3) Image and Gallery - This option is for images only. Unlike the previous options which specify everything in the template, the gallery tag is actually specified as part of the template parameter input. The captions are used as tab titles instead.

Regarding collapsing, I do not believe there is a simply way to collapse a certain number of rows starting with an arbitrary row. However, you can use the group tag to make a predefined group of rows expand/collapse together.
