In the Post Options section you can flexibly customize the appearance and behaviour of each of the post: select or hide the slider above the post, select and set sidebars and their position (or hide the unnecessary ones), set up the display of different parts of the page and the post (information about the author, related posts, a comment block and many more). There are default settings for each post that are specified in the category to which the post belongs. If the settings are not specified in the category, then they are inherited from the overlying category. If there is no settings specified in any of the parental categories, the settings indicated in Appearance > Theme Options – Blog will be used.
