i am using a page template with single facet. it has three panel group layouts with all default settings, two of which are for page header and footer and the middle one for content. I have dropped a bounded task flow which includes fragments as region on a page which uses this template. the region and group is placed in the facet which is used in page template. while rendering the page, page is not using full window. i have a form layout in one jsff which is being displayed in only half of the screen. how can i stretch the page content to be displayed in full browser window.
