Hi Carlos
the test example as below, just use j:HorizontalLayout in j:List, it output
nothing
```xml
<j:List id="list" percentWidth="100" height="100">
<j:beads>
<j:HorizontalLayout itemsExpand="true" />
</j:beads>
<j:dataProvider>
<js:ArrayList id="avengersCharacters" source="[Iron Man, Hulk, Thor,
Captain America]" />
</j:dataProvider>
</j:List>
```
seems j:HGroup has fixed, but j:HorizontalLayout not.
I look at **StyledLayoutBase.itemsHorizontalAlign** setter has logic
`if(hostComponent)`
but **itemsExpand** setter without `if(hostComponent)` that should be the
problem
original StyledLayoutBase.as itemsExpand setter as below.
```actionscript
public function set itemsExpand(value:Boolean):void
{
if (_itemsExpand != value)
{
_itemsExpand = value;
COMPILE::JS
{
if(_itemsExpand)
{
hostClassList.add("itemsExpand");
} else
{
hostClassList.remove("itemsExpand");
}
}
}
}
```
