Ext.form.CheckboxGroup的布局问题

var checkBoxGroupSearch = new Ext.form.CheckboxGroup({
name : 'group',
width:600,
columns : 5,
fieldLabel:'盘点项目',
vertical:false,
items:
[ {boxLabel:'标签码', inputValue:'labelCodes', name:'planColumns',checked:true, readOnly:true,labelAlign:'left'},
{boxLabel:'资产编码', inputValue:'assetCode', name:'planColumns',checked:true, readOnly:true,labelAlign:'left'},
{boxLabel:'资产名称', inputValue:'assetName', name:'planColumns',checked:fieldsValue.indexOf('资产名称')>=0?true : false,labelAlign:'left'},
{boxLabel:'规格型号', inputValue:'specificationModel', name:'planColumns',checked:fieldsValue.indexOf('规格型号')>=0?true : false,labelAlign:'left'},
{boxLabel:'资产用途', inputValue:'assetsUse', name:'planColumns',checked:fieldsValue.indexOf('资产用途')>=0?true : false,labelAlign:'left'},
{boxLabel:'资金渠道', inputValue:'fundingChannels', name:'planColumns',checked:fieldsValue.indexOf('资金渠道')>=0?true : false,labelAlign:'left'},
{boxLabel:'复合数量', inputValue:'compositeNumber', name:'planColumns',checked:fieldsValue.indexOf('复合数量')>=0?true : false,labelAlign:'left'},
{boxLabel:'原值', inputValue:'actualValue', name:'planColumns',checked:fieldsValue.indexOf('原值')>=0?true : false,labelAlign:'left'},
{boxLabel:'净值', inputValue:'netWorth', name:'planColumns',checked:fieldsValue.indexOf('净值')>=0?true : false,labelAlign:'left'},
{boxLabel:'使用状况', inputValue:'useConditions', name:'planColumns',checked:fieldsValue.indexOf('使用状况')>=0?true : false,labelAlign:'left'},
{boxLabel:'责任人', inputValue:'responsiblePersons', name:'planColumns',checked:fieldsValue.indexOf('责任人')>=0?true : false,labelAlign:'left'},
{boxLabel:'所属区块', inputValue:'ownedBlock', name:'planColumns',checked:fieldsValue.indexOf('所属区块')>=0?true : false,labelAlign:'left'},
//{boxLabel:'资产来源', inputValue:'assetSource', name:'planColumns'},
{boxLabel:'自编号', inputValue:'ownNumber', name:'planColumns',checked:fieldsValue.indexOf('自编号')>=0?true : false,labelAlign:'left'},
//{boxLabel:'安装地点', inputValue:'installationLocation', name:'planColumns',checked:fieldsValue.indexOf('installationLocation')>=0?true : false},
{boxLabel:'所属单位', inputValue:'affiliations', name:'planColumns',checked:true, readOnly:true,labelAlign:'left'}

]});
页面如此，显示效果！

所有的文字都重叠了，请问怎么让文字水平显示并且不重叠

{anchor:"20%", boxLabel:'所属单位', inputValue:'affiliations', name:'planColumns',checked:true, readOnly:true,labelAlign:'left'}

这个我用name往action里传值，为什么传不进去

anchor:"20%",   {anchor:"20%", boxLabel:'所属单位', inputValue:'affiliations', name:'planColumns',checked:true, readOnly:true,labelAlign:'left'}
