                    {
                        id: "SPOT",
                        label: "Spot"
                    }, {
                        id: "AFLOAT",
                        label: "Afloat"
                    }, {
                        id: "PREORDER",
                        label: "Preorder"
                    }, {
                        id: "FORWARD",
                        label: "Forward"
                    }
                ]
            }
        },
        {
            renderer: customDropdownRenderer,
            editor: "chosen",
            width: 150,
            chosenOptions: {
                multiple: true,
                data: [
                    {
                        id: "1",
                        label: "Catuai"
                    }, {
                        id: "2",
                        label: "Bourbone"
                    }, {
                        id: "3",
                        label: "Geisha"
                    }
                ]
            }
        }
    ]
});
    
function customDropdownRenderer(instance, td, row, col, prop, value, cellProperties) {
    var selectedId;
    var optionsList = cellProperties.chosenOptions.data;

    if(typeof optionsList === "undefined" || typeof optionsList.length === "undefined" || !optionsList.length) {
        Handsontable.cellTypes.text.renderer(instance, td, row, col, prop, value, cellProperties);
        return td;
    }

    var values = (value + "").split(",");
    value = [];
    for (var index = 0; index < optionsList.length; index++) {

        if (values.indexOf(optionsList[index].id + "") > -1) {
            selectedId = optionsList[index].id;
            value.push(optionsList[index].label);
        }
    }
    value = value.join(", ");

    Handsontable.cellTypes.text.renderer(instance, td, row, col, prop, value, cellProperties);
    return td;
}

Basically, use "chosen" as editor and customDropdownRenderer as renderer. In the chosenOptions, you can set multiple: true if you want to have a multiple select. The data property has to be an array consisting of objects with an id and a label field. You can also use a different renderer. The example renderer (customDropdownRenderer) will simply output a comma separated list of the appropriate labels.
