Concentrate groupped pageItems by script

That is AWESOME!

Just for the record, I tried it with images in a Data Merge. Unfortunately it doesn't work in that instance (if "fit frames to image" is selected, the script won't move the text accordingly). I think it has something to do with the image changing size without the focus being put onto the image.

Still a hell of a technique though!

Hi Marcin,

Here is a draft code you may work from.

#targetengine magnetGroupRectangle

function follow()  
{    
    const T=0, L=1, B=2, R=3;

    if( !app.properties.activeDocument ) return;
    if( !app.properties.selection ) return;
    if( 1 != app.selection.length ) return;
    
    var a, i, every, b, i, dx, dy
        r = app.selection[0],
        g = r.parent;

    if( !( r instanceof Rectangle ) ) return;
    if( !( g instanceof Group ) ) return;
    if( 3 != g.pageItems.count() ) return;

    a = (every=g.textFrames.everyItem()).getElements();
    if( 2 != a.length ) return;

    b = every.visibleBounds;
    i = +(b[0] > b[1]);
    
    r = r.visibleBounds;

    // Right magnet
    dx = r-b;

    b=r;

    b=r;

    b+=dx;

    b+=dx;


    // Bottom magnet
    i = 1 - i;
    dy = r-b;

    b=r;

    b=r;

    b+=dy;

    b+=dy;

    
    a[0].visibleBounds = b[0];
    a[1].visibleBounds = b[1];
}  

(function(tasks,name,rate,callback)  
{  
    var t = tasks.itemByName(name);  
    if( t.isValid )
    {
        t.eventListeners.everyItem().remove();
        t.remove();
    }  
    tasks.add({name:name, sleep:rate})
       .addEventListener(IdleEvent.ON_IDLE, callback, false);  

})(app.idleTasks,'magnetGroupRectangle',15,follow);

Here is what it does:
