i have added in application.xml at the item-content group this param
<param name="item_grid_layout" type="list" default="1" label="Item Grid Layout">
<option value="1">Long Media Left</option>
<option value="2">Long Media Right</option>
</param>
and i want to access it from the teaser.php file.
i'm calling it from teaser.php in renderer
$view->params->get('content.item_grid_layout') but i get NULL
any ideas why this is not working? i followed the instructions in yootheme documentation http://yootheme.com/zoo/documentation/developers/extend-content-parameters
