level
Hierarchies can have different numbers of levels. For example, a Product hierarchy containing, All Products, Product Groups,
Product Sub-groups and Products is a four-level hierarchy. A Time hierarchy containing Year, Quarter, Month, Week and Day
is a five-level hierarchy. In the list designer you can specify that only list elements at a particular level of the hierarchy
are displayed (for example, only product sub-groups). In the List Designer you can specify the level by its name. Levels also
have numerical identities. The parent or root level of a hierarchy is at Level 1 and the levels and sub-levels are Level 2,
Level 3 etc. In the Client List Designer, level-based selection uses level numbers instead of name. By using the GETLEVEL
function with conditional formatting, you can specify a level by its number and give it a different format from the other
levels.
