On May 23, 2017, we published version 1.25.1 of the table grid editor. This release is introducing the multi-level cascading select field.

Now you can create a custom field that can contain many drop-downs. Each drop-down list is built dynamically – using SQL queries.
These queries can reference the values of other levels, such that complex cascading effects can be created.

Give it a try – check the marketplace for more information
