Is there an indesign script to arrange multiple objects in a matrix?

[dublove]

can control the spacing and size.
The size can be controlled by calling the object style.
For example, I want to arrange 6 plates into: 2 columns and 3 rows.
The horizontal spacing is 4mm, and the vertical spacing is 8mm.

It’s easy enough to remove the X, Y preference from the dialog, but the grid is keyed off of the upper left corner of the selection and not its center. So in this example the new arrangment would not be centered on the original selection:

The grid will start from the upper left of the original selection

/*
* Arranges a selection of objects into a grid starting from the selection’s upper left
* Version 1.5
* Rob Day 2020-2021
*/


//check for a selection
var s = app.activeDocument.selection;
if (s.length > 1) {
    makeDialog();
} else {alert("Please Select Some Objects.")}

//result variables
var xoff, syoff, col, row, xgut, ygut; 

/**
* Make the export settings dialog 
*  
* 
*/
function makeDialog(){
    var mw = 90;

    //the dialog name
    var theDialog = app.dialogs.add({name:"Arrange Matrix", canCancel:true});
    with(theDialog){
        with(dialogColumns.add()){
            with(borderPanels.add()){
                with(dialogColumns.add()){
                    staticTexts.add({staticLabel:"Columns:"});
                    staticTexts.add({staticLabel:"Rows:"});
                    staticTexts.add({staticLabel:"Column Gutter:"});
                    staticTexts.add({staticLabel:"Row Gutter:"});
                }
                with(dialogColumns.add()){
                    var nCol = integerEditboxes.add({editValue:2, minWidth:mw});
                    var nRow = integerEditboxes.add({editValue:2, minWidth:mw});
                    var colGutter = measurementEditboxes.add({editUnits:MeasurementUnits.MILLIMETERS, editValue:0, minWidth:mw});
                    var rowGutter = measurementEditboxes.add({editUnits:MeasurementUnits.MILLIMETERS, editValue:0, minWidth:mw});
                }
            }
        }
    }
	
    var dResult = theDialog.show();
    if(dResult == true){
        col = nCol.editValue;
        row = nRow.editValue;
        xgut = colGutter.editValue;
        ygut = rowGutter.editValue
        theDialog.destroy();
        makeMatrix();

		theDialog.destroy();

Hi dublove,

Firefox is working as well on my Windows 10 machine:

Also running the script on a selection of items:
