# Hiding checkbox of LayerNode in GeoExt?

I would like to hide/remove the checkbox of a LayerNode, since I need to have it always on display.

Is there any sort of option to do this, or must I use the Ext object hierarchy to locate the checkbox object and remove it?

treeNode.getUI().checkbox.hidden = true;
Where treeNode is an object of the type GeoExt.tree.LayerNode.
