Hi Tony,

Sorry for my carelessness， the scrollbar is OK, I forgot to adjust the height

For Inline editing, it based on the definition of colModel, so to some column, all rows have the same editor type, could tree grid support custmization for each row, it meas that the column value in row a is drop down list, in row b it's a input text.

Great job, thank you very much! I am trying to integrate it into my project
