We need 3 level hierarchy kind of custom field.

[Jason Liu]

We want to have a custom field who has 3 levels. I know that select list cascading has two levels. Is there any way to make 3 levels happen? I want to have the values like version 1, version 1.1 and version 1.1.1 ... If I choose version 1, then second level will show 1.1, 1.2 etc. and the third level will show 1.1.1, 1.1.2 etc.
