What Javascript library I should use? Please help me
Actually I need a help from you to choose a javascript library depending on my requirements.

My requirement is, I will create an unlimited directory system. In every directory there can be subdirectory or person's information with image. This directory system will be database driven. I will use mostly use php for the most parts of this application. But for this portion, i want to use a javascript library. I need the directory with a good GUI built-in, some simple animation and ajax supported ofcourse. Moreover, This portion should be load very fast.

So, which javascript library i should use? At first i was thinking about ExtJS. But it is heavy weight for me. So, i think you understand my requirements? If any other question, please just ask me. This is some urgent requirements. So, after your suggestion i will learn about that js library and then work with the application. So, help me please. Have a nice day. bye
