My problem is when i select multiple column and row and drag, the column A is properly generating because I am generating to that particular column only. the other columns are not autofill properly.
Handsontable does not provide this type of ‘after drag’ sequences, but it’s a part of our to-do list.
If you would like to develop this feature by your own we would be happy to help with this but the support services are a part of our commercial offer. The basic support includes help in all the issues connected with Handsontable (like preparing recipes for typical use cases, fixing bugs, etc.), but doesn’t cover development on-demand like custom integrations, implementations in specific systems etc.
