Textarea column in Dash AG Grid

Hi @wen

Thanks for providing more information about your use case. I think I have a better understanding of what you are trying to achieve.

In your original post, you wanted users to see the changes. Would something like this be helpful? It shows the changes in a Tooltip. You can find it in the Tooltip tutorial here:


Also, note that you don’t need to make your own custom component for textarea. You can use the built in component agLargeTextCellEditor.
See an example here:
