Could you fill out the bug report template so that I can understand your issue better please.

Here it is again below:

### Steps to reproduce


### What is Expected?


### What is actually happening?

Steps to reproduce

I used this template http://codepen.io/pen?template=qrjOpX

And added this code to better undestand my situation:
[css]

.column:nth-child(1) {
height: 200px !important;
}

[js]

isCentered: true, // new Shuffle

What is Expected?

I expected that all blocks will be centered.
https://codepen.io/OceanITs/pen/EwqQXN (with fix shuffle.js)

What is actually happening?

I got incorrect left position for some blocks.
https://codepen.io/OceanITs/pen/qPexBq (your can just compare)

Why is actually happening?

shuffle.js (dist)

Offset (line 785) must be the same for each block. (Maybe i wrong but it works for my situation)
It not happend for some blocks because lastItem.left (line 784) different in rowMap forEach function.

My Decision

shuffle.js (dist)

Get offset only from first rowMap, and comment others:

comment lines 784,785
before line 780 add

var lastItem = rowMap[0][rowMap[0].length - 1];
var end = lastItem.left + lastItem.width;
var offset = Math.round((containerWidth - end) / 2);

I came across the same problem.
On several rows, the first item on the left have an incorrect horizontal position.

I applied the fix proposed by OceanITs, which seems to work.

Can this be implemented?

[Vestride]

Yes, there could be a fix implemented, but I'm not focused on Shuffle at the moment.

Pull requests that don't just change the generated dist files are welcome.

[superjunky]

Understood.
I'm not a javascript-wizard.. Perhaps the topicstarter is willing to implement it.
