Hi Team,

I have a power table and I want to dropdown for "version" column(it will fetch multiple version), depending on selected grade 1st column.  
please refer below diagram-

How can I do this, any idea?

> The much more efficient solution is to embed a custom editor, which will lookup the datasets dynamically whenever it’s appropriate. I’ve got a very simple example of this below; the project has an editable ‘Options’ dataset, and the available options in column B in the editable table will be dynamic based on the value in column A. The relevant code is here: root = self from javax.swing import JComboBox, DefaultCellEditor, DefaultComboBoxModel class CustomCellEditor(DefaultCellEditor):…

Here's a starting point of how to make multiple-layered custom dropdown options.

on which event I need to write this code?  
because I want versions of selected "grade" and the "grade" will get after selecting the row and after that I want to bind the dropdown data.  
by default, there is one row with single version but when user double clicks on "version" column dropdown should appear with multiple versions.

There's a project file in the linked post; import it and you can see the full setup, because it involves more than one event hook on the table.
