The Plugin has been modified to a new name - VMCustom - VM Product Cart Variants (this should help avoid confusion caused by old name of DropBox as this did not reflect functionality) Tested on VM3 using J3 php5.6 and php7and J2.5. Its functionality is based on the original DROPBOX by PRO with greater functionality

This plugin does not handle stock control at a variant level
