hi, these words are as per above link(jaspersoft theme.pdf) "A theme is a collection of CSS files and associated images that specify the appearance for all or part of the user interface. A theme only controls how the interface appears, for example fonts, colors, spacing, lines, and image elements of the UI. It does not control what appears, such as the contents of menus or the effect of clicking a button." MY QUESTION??? if we want to change the content of the menus and effects of the clicking a buttion(expand/collapse by buttion),where/which files want to be change,how to be change??? pls update any one,ur help is most appreciatble... :)
