    <p>It is not possible to add a column to the jqGrid dynamically. You have to recreate the whole grid with <code>colModel</code> having one column more. If you use separate <code>colNames</code>, then the size of the array have to be increased too. You can use <a href="http://www.trirand.com/jqgridwiki/doku.php?id=wiki:methods#add_on_grid_methods" rel="noreferrer">GridDestroy</a> for example to destroy the existing grid. The usage of <code>jQuery.Remove</code> or <code>jQuery.Empty</code> instead is also possible.</p> <p><strong>UPDATED</strong>: It seems to me that <a href="http://www.trirand.com/jqgridwiki/doku.php?id=wiki:methods#add_on_grid_methods" rel="noreferrer">GridUnload</a> is better for your porpose. I created <a href="http://www.ok-soft-gmbh.com/jqGrid/RecreateGrid.htm" rel="noreferrer">small demo</a> which demonstrate how one can recreate a grid. To be able to use <a href="http://www.trirand.com/jqgridwiki/doku.php?id=wiki:methods#add_on_grid_methods" rel="noreferrer">GridUnload</a> or <a href="http://www.trirand.com/jqgridwiki/doku.php?id=wiki:methods#add_on_grid_methods" rel="noreferrer">GridDestroy</a> you have to verify that you include grid.custom.js in your project (if you use developer version of the jqGrid) or you have checked "Custom" "Additinal methods" on the <a href="http://www.trirand.com/blog/?page_id=6" rel="noreferrer">jqGrid download</a> page.</p> <p><strong>UPDATED 2</strong>: One can use <code>addColumn</code> method which can be downloaded from <a href="https://github.com/OlegKi/jqGrid-plugins" rel="noreferrer">here</a> (see <code>jQuery.jqGrid.addColumn.js</code>). The method is still in beta phase. One can find some demos which shows how to use the method <a href="https://github.com/OlegKi/jqGrid-plugins/tree/master/demos" rel="noreferrer">here</a> (see <code>addColumnX.htm</code> examples).</p>

    1. COThanks, but I can't find how to use GridDestroy. Can you help me with a small example? `jQuery("#list").jqGrid('GridDestroy');` says that the function is undefined (GridDestroy)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
