I've seen on some sites (but cannot think of any now to give as example) when there is a text link on a page somewhere. When the user clicks on the link a box/content appears immediately without appearing to reload the page.
In essence it seems that the element (whether a DIV, form, etc) has been on the page initially, but hidden from view. Clicking on the visible text link then makes the element visible.
Do you know what I mean, and if so are you able to point me to any tutorials or examples of this working because I think it'd make a really nice addition to my site in the form of a help section - there is a link to 'help' and when pressed a sidebar immediatley becomes visible.
Thanks for your help
