Page builder for Foundation: small dev-issue

Hi,

I am currently modifying the siteorigin-panels.php so the page builder will generate Foundation CSS.

I am almost there! :) But I need a little push from you guys. I think it is a small issue.

The .panel-grid class is replaced by the .row class. Now I only need to replace the .panel-grid-cell class by the large-X classes provide by Foundation, where X is the result of a calculation based on the width of a cell.
eg:
if width = 33% => X = 4
if width = 50% => X = 6

This is all working pretty well. Only issue is that when I work with different rows, the X is always calculated based on the column-widths of the first row!

How can I make sure X is calculated, based on its current row?

This is what I have until now in the function siteorigin_panels_render:

foreach ( $cells as $ci => $widgets ) {
    // foundation
    $cell = $panels_data['grid_cells'][$ci];
    $width = round( $cell['weight'] * 12, 0 );
		
    // Themes can add their own styles to cells
    $cell_classes = apply_filters( 'siteorigin_panels_row_cell_classes', array('panel-grid-cell', 'large-' . $width), $panels_data );
...

$cell should be ‘$cell of the current row’

Hope you guys can help me out here… Almost there :)

thx!
