Hi Sathish,
<b>Breadcrumbs can be used for:</b>
> inform users about their current position within a hierarchy, such as an application, a directory, a Website, or a document.
> Allow for easy navigation back to the starting point, or to other levels within a hierarchy
Software applications and information in the Web are often organized hierarchically: General information may lead to more specific information, thus creating an information hierarchy. The breadcrumb control informs the user about the path to a specific content within such a hierarchy. For example, hit lists typically include a breadcrumb to inform users about the hierarchy level of a search result and therefore are guides to the list items. If the breadcrumb uses links in the path description, the user can move to a specific folder or topic.
An item in the breadcrumb chain is called breadcrumb item. Breadcrumb items can be defined by models or manually.
If the breadcrumb line becomes longer than the width of the browser window, the breadcrumb is word-wrapped like a text line (figure 2). The wrapping is done at word separators, such as blanks. If there is no word separator in the breadcrumb item string, the breadcrumb will wrap behind the breadcrumb item separator ">".
<b>Types:</b>
Breadcrumbs can be displayed as simple path information, as a chain of clickable locations within the hierarchy, or as one link that is described by the path information.
The breadcrumb type is set through the attribute behavior: value SINGLELINK creates a breadcrumb, where the whole path is selectable; value DEFAULT creates a breadcrumb, where each item can be linked independently.
<b>Usage - Types</b>
Use the different breadcrumb types for the following purposes:
> Use path information breadcrumbs (figure 3 top) for indicating the location of files inside a hierarchy.
Example: A list of search results not only shows the hits themselves but also their paths.
> Use independently linked breadcrumbs (figure 3 center) if you want to allow users to move up and down within a hierarchy, or to jump to a certain category. The last breadcrumb always shows the actual page and is no link.
> Use the whole breadcrumb path as one single link (figure 3 bottom) to inform users about the location of a link target ( = the last breadcrumb item) inside a hierarchy.
