'radiogroup' 的小问题.

,{
xtype: 'radiogroup',
itemCls: 'x-check-group-alt',
fieldLabel: 'Custom Layout
(w/ validation)',
allowBlank: false,
anchor: '95%',
items: [{
columnWidth: '.25',
items: [
{xtype: 'label', text: 'Heading 1', cls:'x-form-check-group-label', anchor:'-15'},
{boxLabel: 'Item 1', name: 'rb-cust1', inputValue: 1},
{boxLabel: 'Item 2', name: 'rb-cust1', inputValue: 2}
]
},{
columnWidth: '.5',
items: [
{xtype: 'label', text: 'Heading 2', cls:'x-form-check-group-label', anchor:'-15'},
{boxLabel: 'A long item just for fun', name: 'rb-cust2', inputValue: 3}
]
},{
columnWidth: '.25',
items: [
{xtype: 'label', text: 'Heading 3', cls:'x-form-check-group-label', anchor:'-15'},
{boxLabel: 'Item 4', name: 'rb-cust3', inputValue: 4},
{boxLabel: 'Item 5', name: 'rb-cust3', inputValue: 5}
]
}]
}

是这个着一大组都必须选定.而且样子也比较好看.
我想把每个都能是必添的'rb-cust1','rb-cust2','rb-cust3'都必须填写.
大家有什么办法么
[b]问题补充：[/b]
不行.一点效果都没有yourgame.还有别的办法么.着就是ext-3.0.0的那个例子中的一段..
[b]问题补充：[/b]
效果是这样的.(你可以看图,也可以看url http://www.extjs.com/deploy/dev/examples/form/check-radio.html)

url的最后一项是
Item 1
Item 2
A long item just for fun
Item 4
Item 5

着五个只要任意添一项就可以.

但我想Heading 1,Heading 2,Heading 3都是必添项
也就是说,
Item 1
Item 2
中必须有一个必添
Item 4
Item 5
中必须有一个必添
A long item just for fun
必须选种

才能通过allowBlank: false的验证.

[code="js"]
Ext.onReady(function(){
var individual2 = [{
bodyStyle: 'padding-right:5px;',
items: {
xtype: 'fieldset',
autoHeight: true,
defaultType: 'radio', // each item will be a checkbox
defaults:{hideLabel:true},
items: [{
xtype: 'label', text: 'Heading 1'
}, {
boxLabel: 'Dog',
name: 'a'
}, {
labelSeparator: '',
boxLabel: 'Cat',
name: 'a'
}, {
checked: true,
labelSeparator: '',
boxLabel: 'Monkey',

给你的代码没有测试,我本机示例已经做出来了

试试看
[code="js"],{
xtype: 'radiogroup',
itemCls: 'x-check-group-alt',
fieldLabel: 'Custom Layout
(w/ validation)',
allowBlank: false,
anchor: '95%',
items: [{
columnWidth: '.25',
allowBlank :false,//注意这里,
items: [
{xtype: 'label', text: 'Heading 1', cls:'x-form-check-group-label', anchor:'-15'},
{boxLabel: 'Item 1', name: 'rb-cust1', inputValue: 1},
{boxLabel: 'Item 2', name: 'rb-cust1', inputValue: 2}
]
},{
columnWidth: '.5',
allowBlank :false,//注意这里,
items: [
{xtype: 'label', text: 'Heading 2', cls:'x-form-check-group-label', anchor:'-15'},
{boxLabel: 'A long item just for fun', name: 'rb-cust2', inputValue: 3}
]
},{
columnWidth: '.25',
allowBlank :false,//注意这里,
items: [
{xtype: 'label', text: 'Heading 3', cls:'x-form-check-group-label', anchor:'-15'},
{boxLabel: 'Item 4', name: 'rb-cust3', inputValue: 4},
{boxLabel: 'Item 5', name: 'rb-cust3', inputValue: 5}
]
}]
} [/code]

我还没有明白你的意思,请描述清楚
