Quick Short Javascript (or other language)

I need a very simple script written. I am going to have a lot of bullet points. Each bullet point will have extra text, like an extra description. E.G.: . Bullet 1 . Bullet 2 . Bullet 3 . Bullet 4 etc... If you click on one of the Bullet Points (the point or the actual text) I would like it to expand to show the extra text. E.G.: . Bullet 1 . Bullet 2 - Bullet 2 expanded. Bullet 2 expanded. Bullet 2 expanded. Bullet 2 expanded. Bullet 2 expanded. Bullet 2 expanded. Bullet 2 expanded. Bullet 2 expanded. . Bullet 3 . Bullet 4 etc... It also needs to be possible to expand more than one point at one time. E.G.: . Bullet 1 . Bullet 2 - Bullet 2 expanded. Bullet 2 expanded. Bullet 2 expanded. Bullet 2 expanded. Bullet 2 expanded. Bullet 2 expanded. Bullet 2 expanded. Bullet 2 expanded. . Bullet 3 - Bullet 3 expanded. Bullet 3 expanded. Bullet 3 expanded. Bullet 3 expanded. Bullet 3 expanded. Bullet 3 expanded. Bullet 3 expanded. Bullet 3 expanded. . Bullet 4 etc... There also needs to be 2 links at the top of the list. 1st = Expand All, 2nd = Collapse All. I will need to add many of these points, so needs to be simple to expand. I dont know if it is best to have divs that are initially hidden and then are made visible, or some other method. Please post your description along with your bid. Please note that your bid will be hidden, so that you dont have to worry about putting private information there. Thank you for your time, and I hope that I have not missed anything out!! Cheers Matt Garnham
