How to expand only rows

Hello, 
 
Thank you for reaching out to us.
 
1. We would like to point out that Flexmonster provides several ways of how the options can be set. 
 
2. Please note that Flexmonster provides the following expand options:

    1) expandAllData to expand everything
    2) expandData to expand a certain hierarchy

    Regarding expanding only rows, we kindly advise the following approach:
 
    1) Check what is selected in the rows section. 
    2) Expand the rows by using expandData for each item that is present in rows.
 
3. Speaking of column width - we have default column width, however, it is possible to change the width by dragging the column headers and saving the report.
 
Please let us know if this works.
 
Best Regards,
Vera
