Array in dropdown (Handsontable)

Question

I want to put an array data in a dropdown with Handsontable. So, I created a little array like this :

var array_dropdown = ['Hello','test','lison','flag'];

And here is my HOT :

var container = document.getElementById('tab_traitement');
var hot = new Handsontable(container, {
    data: data_traitement,
    minSpareRows: 1,
    rowHeaders: false,
    colHeaders: false,
    contextMenu: true,
    height: 300,
    width: 810,
    colWidths: [200, 200, 200, 200],
    cells: function(row, col, prop) {
        var cellProperties = {};

        if ([0].indexOf(row) !== -1 && col >= 0) {
            cellProperties.readOnly = true;
        }
        return cellProperties;
    },
    columns: [{}, {}, {}, {
        type: 'dropdown',
        source: [array_dropdown] //Here, I'm trying to get the array data
    }]

});

Can someone help me please ?

In source option you don't need []. This will make the array two-dimensional, as array_dropdown is already an array.

source: array_dropdown // Don't need `[]` here
