jQuery UI tabs is one of my favorite jquery plugin I use in most of my projects. It is so simple to use and it degrade gracefully. It has some very nice features and the events are really helpful.
However while I was working on a project where all the tabs contents are dynamic i.e user perform a search and than the results will be grouped up in tabs but the problem was that you never know how many tabs do you need as it can be just 1 or it can be 50+. The problem is that you should know the number of tabs so you can give a width to the wrapper so all tabs can fit in one row.
Unfortunately in my case I could not use it because I cannot give the wrapper a width of like 1000px for many tabs. If you give the wrapper a fixed width, the tabs will try to adjust it self in as many rows as it can to adjust all the tabs, something like this:
