powerful. However I'm having problems to get it working.

First of all, as said in the topic, since the content will be served from the server (PHP), and I want to use it to

display different lists of items, I need that both properties colNames and colModel will be served dynamically.

So, this is how I set it up in a js file:

$(document).ready(function() {
    $("#listing").jqGrid({
    	datatype: "clientSide",
    	height: 500,
        colNames: namesList,
        colModel: modelList,
       	multiselect: true,
        viewrecords: true,
       	caption: "Test"
    });
});

Here's an example in PHP of an item type whose records must be listed. I set its corresponding column

names and how will they be displayed:

$colNames = array('Id', 'Title', 'Featured', 'Language', 'Date created', 'Date modified', 

'Date published', 'Status');
        $colModel = array(
            array('name' => 'id_article', 'id' => 'id_article', 'width' => 60, 'sorttype' => 'int'),
            array('name' => 'title', 'id' => 'title', 'width' => 450, 'sorttype' => 'text'),
            array('name' => 'featured', 'id' => 'featured', 'width' => 60, 'sorttype' => 'int'),
            array('name' => 'language', 'id' => 'language', 'width' => 60, 'sorttype' => 'text'),
            array('name' => 'date_c', 'id' => 'date_c', 'width' => 120, 'sorttype' => 'date'),
            array('name' => 'date_m', 'id' => 'date_m', 'width' => 120, 'sorttype' => 'date'),
            array('name' => 'date_p', 'id' => 'date_p', 'width' => 120, 'sorttype' => 'date'),
            array('name' => 'status', 'id' => 'status', 'width' => 60, 'sorttype' => 'int')
        );

This is how I dynamically create the variables I need for colNames, colModel and the data to display

(enclosed with script tags):

var namesList = < ?php echo json_encode($colNames)  ? >, 
    modelList = < ?php echo json_encode($colModel)  ? >, 
    data = < ?php echo json_encode($lista)  ? > 
    
for(var i = 0; i <= datos.length; i++) {
    $('#listing').addRowData(i+1, data[i]);
}

With this all configured, I just get to build the background of the grid with the column names.

No data is displayed. Could you please help me?
