Rendering a command column as a drop down

Hi, I have a QCBMagritteReport (a subclass of MAReport) with a command column with options to perform on each row: addColumn: (MACommandColumn new addCommandOn: self selector: #edit: text: 'Edit'; addCommandOn: self selector: #delete: text: 'Delete'; addCommandOn: self selector: #validate: text: 'Check'; yourself) This works well, however I would like to see a Bootstrap drop down button as opposed to individual links being shown. I've experimented with QCCommandColumn but without success (it needs something in its component instance variable but I'm clueless as to what). Is there a specialised renderer for this I can use or should I implement my own? Thanks for reading. Roger
