Hi Thiago, Thanks for your answer.
Some more information: - In the data, what distinguishes the first level from the second? First level is an alphanumeric code Second level options start with the first level code + "-" + additional code - It's a static list to choose from - Will choosing a checkbox in the first level change the options in the second? Yes, if level one is chosen then second level options are automatically chosen as well Is there any example or sample solution which takes Checklist core component but with modifications that you can point me to? Thanks again :=) Adriana
