I'm working on a plugin in CKEditor which have as a goal to hide or show element depending on which of my check box is checked. I have those element defined : 

```
contents :
            [
                {
                    id : 'tab1',
                    label : 'Configuration Basique',
                    elements :
                    [
                        {
                            type : 'checkbox',
                            id : 'check',
                            label : 'Vers une page web',
                            'default' : 'unchecked',
                            onClick : function(){

                            }
                        },
                        {
                            type : 'text',
                            id : 'title',
                            label : 'Explanation',
                        }    
                    ]
                },
                {
                    id : 'tab2',
                    label : 'Advanced Settings',
                    elements :
                    [
                        {
                            type : 'text',
                            id : 'id',
                            label : 'Id'
                        }
                    ]
                }
            ],

```

so now what i would like to do is to hide no disable the text input with the label and print it only when the box is checked. So i've seen that i should use something like that :

```
onLoad : function(){
                this.getContentElement('tab1','title').disable();
        },

```

but the thing is i don't want to disable it i want to hide and then print it if the user check the box (which is why i put a onClick function in my checkbox). i've tryed to use the hide() function but it doesn't work and also the setAttribute('style','display : none;')
