jsgrid is configured by setting options on various levels to control the grid behaviour and features. Typically, this is done right in the constructor:

$("#grid").jqGrid({
    // configure backend URL
    url: 'example.php',
    // Enable the caption layer
    caption: 'My first jsgrid'
});

You can find a reference of all options under the links on the right.

Changing Global Defaults

If you want to re-use settings across multiple grids, you can also set options globally:

$.extend(true, $.jgrid.defaults, { caption: 'The default caption for all grids' });

Of course, the global settings have to be changed before instantiating the grid, and global settings will get overwritten by options set directly in the grid constructor:

$.extend(true, $.jgrid.defaults, { caption: 'This will get overwritten' });
$("#grid").jqGrid({
    url: 'example.php',
    caption: 'This will be rendered'
});
