Description

Allow users to break up long lists of items into separate pages.  They should be able to decide if they want paging and how many per page.

Sakai has page navigation now -- "List Navigator UI Component" in the Sakai style guide.  The default for how many items to show on a page varies.  How many makes sense depends on context, how many total items, what type of items, etc.  The idea here is to make this navigator remember the users last setting (across sessions).  That way they set if for what makes sense given the current situation and it is persistent.  As things change for them they simply change the setting to meet current needs and again it's persistent until they need to change it again.  Currently this is a "one size fits all" default and many users have to change it every time they visit a particular page.

Problems with current Sakai widget 

  • Often users change this setting every time they visit a particular page/tool.  As explained above, the default setting for how many to show on a page doesn't always make sense.
  • Related to above, widget doesn't remember users setting from previous session.
  • Widget takes up significant (extremely valuable) real estate at top of page.
  • Current widget is displayed even if the number of items is less than is required for paging (i.e. there are 9 items listed and paging kicks in by default after 10).

Use Cases / Requirements for new component

  • User can choose to break up long lists of information into several pages.
  • Show users how many there are and where they are in the list (i.e. viewing 10 - 20 or 2,356)
  • Allow users to "show all". 
  • Allow users to decide how many to show on each page.  The best option will depend on a variety of dynamic circumstances (how many in list, what they are doing with the items, whether they need to see the items globally...)
  • Remember users last setting (from previous session).  This should be specific to the instance of the paginator.

References / Competitive Analysis

NOTE:   Many of the below are for search navigation so should used strictly as a reference for more robust web application pages where users need to actually do something with the items in a list (other than just choose one).
