Blog owners are becoming increasingly interested in using the new Blogger offering, Static Pages (aka "Pages" in Blogger speak), in their blogs. Recently, we've seen blog owners who like to publish blogs with large displays asking about another new Blogger feature, Jump Break. Some blog owners would like to use Jump Break to summarise their static pages.
Jump Break, the Blogger solution for auto summarising posts, displays an entire post, when the post is being displayed in individual post mode. When a post is being displayed in multi post mode - archive retrieval / label search / main page - the summarised portion of the post is displayed, with a "Read More" link leading to the individual post display. The code is very simple - the group mode, summarised post links to the individual mode, full display post.
There is no option to display static pages in a group, with other static pages. A static page displays in one mode - as a single, static page. With a static page displayed in only one mode, there's no way to use a Jump Break in a static page.
If you want to summarise selected posts, indexed from your tabs bar, make a custom pages / posts / label search index. Then, you can index any number of label retrievals, each label retrieval with a number of posts - and each post can contain a jump break.
Just don't try to add a jump break into a static page.
