hi, help me add a checkbox to formIt  
i created preHook

```auto
$hook->setValue('color',json_encode(array('blue','red','green')));
return true;

```

and I go out of the form

```auto
<label>Color /[[!+fi.color]]</label>
<input type="checkbox" name="color[]" value="blue" [[!+fi.color:FormItIsChecked=`blue`]] > blue
<input type="checkbox" name="color[]" value="red" [[!+fi.color:FormItIsChecked=`red`]] > red
<input type="checkbox" name="color[]" value="green" [[!+fi.color:FormItIsChecked=`green`]] > green

```

but the checkbox is not selected  
and in [[!+fi.color]]  
it displays ‘[“blue”,“red”,“green”]’  
how to make them become Checked

I can’t reproduce this issue.  
It seems to work correctly when I test it.

Doesn’t work if used FENOM

```auto
{'!FormIt' | snippet : [
                      'preHooks' => 'foreach'
                    ]}

```

if you use standard output everything works

```auto
[[!FormIt?
                    &preHooks=`foreach`
                 ]]

```

I still can’t reproduce this.  
When I test it, it does work. Even when using Fenom for the _FormIt_ snippet call.
