A multi select list allows one the luxury of multiple options in one object. However the same is not available in Datawindows. Storing a multitude of options as a single columns data has always been a challenge. The previous method followed was by creating a number which used exponential values for each option i.e. The maximum number was 2ⁿ  -1 for N  options. However there was a need to create 2 -3 functions for each such column. Thus, if one data window has to offer such choices for many columns, there was huge overhead of maintaining the code. One had to remember the exact value (2^x) assigned to each option. The exact calculations had an additional overhead for the CPU.
