Then add the root to the TreePanel with the "root:" paramater: // var tree = new Ext.tree.TreePanel({ region: "west", frame: false, title: "Table of Contents", root: layerRoot, enableDD: true, collapsible: true, height: "60%", expanded: true, autoScroll: true }); // Ryan On 9/1/2010 11:08 AM, Andrew Stewart wrote: Trying to find a good example on how to add multiple LayerContainers to my TreePanel but so far unsuccesful. I've defined two LayerContainer controls like so - var layerList_Labels = new GeoExt.tree.LayerContainer({ text: 'Labels', layerStore: mapPanel.layers, leaf: false, expanded: false, loader: { filter: function(record) { var myarr = new Array(); myarr[0] = record.get("layer").name.indexOf("Overview Streets"); myarr[1] = record.get("layer").name.indexOf("Quadrant Streets"); if(myarr[0]==-1 && myarr[1]==-1) { return false; } else { return true; } } } }); var layerList_Labels2 = new GeoExt.tree.LayerContainer({ text: 'Labels2', layerStore: mapPanel.layers, leaf: false, expanded: false, loader: { filter: function(record) { var myarr = new Array(); myarr[0] = record.get("layer").name.indexOf("Overview Streets"); myarr[1] = record.get("layer").name.indexOf("Quadrant Streets"); if(myarr[0]==-1 && myarr[1]==-1) { return false; } else { return true; } } } }); Now I am just unsure exactly how to add these both to my TreePanel - i've tried adding them both to root, or trying to use children but it is not showing up. Any help greatly appreciated. var layerTree = new Ext.tree.TreePanel({ title: '', renderTo: 'legend', root: layerList_Labels, enableDD: true, applyLoader: true }); ________________________________ This e-mail is intended for the original recipient(s) only.
