Component goes out of another component - apache-flex

Question

If I drag a textInput from a component and drop it near the end of the another component, the textInput goes outside of the dropZone.
Any ideas how to resolve this problem?
thanks

Answer 1

On your layout object, set clipAndEnableScrolling to true. This will cause the layout to clip all content that is ouside the bounds of the containter. If you need to scroll, then you still need to wrap your group in a scroller.
<s:BorderContainer width="100%" height="100%">
<s:layout>
<s:VerticalLayout gap="10" clipAndEnableScrolling="true"/>
</s:layout>
<s:Label text="TextInput" mouseMove="textInput_mouseDownHandler(event )" dragComplete="dragCompleteHandler(event)" />
</s:BorderContainer>
clipAndEnableScrolling is a property on all the layouts, VerticalLayout, HorizontalLayout, and BasicLayout to name a few.
