Jtarget updated to version 1.1 to load template.css in the Iframe head.
Jwrapperbot is a native 1.5 content plugin enabling you to wrap an external site/script or a component via an IFrame in an Article. Parameters are available as general and locally. Instructions available when editing the plugin. Please read carefully.
When used to load a component, you should install its companion, Jtarget, which is a system plugin using the target parameter of Jwrapperbot to add a Base target tag in the IFrame. The tag added is of the type _top (or _blank) depending if you want to load a link from the Iframe replacing the existing window or in a new window. New in 1.1: as the template.css is not loaded natively, Jtarget now takes care of it.
Decompress the package first and install the 2 plugins separately.
Suggestion: if nevertheless you have some issues, please start a thread in the forum

August 11, 2008: JTarget now updated to load other css than the main one in the Iframe. This is due to the 1.5 templates tendancy to need many CSS depending on parameters set for the template. This is useful only if Jwrapperbot is used to load a component.
