Drop Down ABAP Reporting

Dear Guys

Is it possible to do drop down list programming in ABAP as it can be done in Logistic Information System If yes then how and where I can found documentation.

Note down I dont want to use any SAP tool and want to do it with ABAP Language.

E.g.

A Main record is showing in first line of List with a drop down button. When user prsses that button then a detailed list will show under the first line containing remaining details records.

I know that button can be controled by AT User Command but how a detailed list with futher records can be shown exactly below the first line.

Please also note that I dont want to display the detailed records in a next list. I just want the details records under the first line when user presses the drop down button.

Tnx
