[jQuery] Any jquery plugin to help in displaying popups (divs above everything)?


I am having to display some popup divs (some divs which appear when
user clicks something) in my project. Now, I am facing numerous issues
relating to positioning of the divs, making the div appear over
everything etc. etc. in different browsers. This has become a serious
problem. I badly need a plugin if available. I have seen the thickbox
plugin but that is not ecaxtly what I want. I want the plugin to be
positioned wherever I want and the background should not deactivate.
Please help me with anything you know.
