Additional Customization

The collapsed bar position is decide by LayoutRegion.getCmargins(). Therefore, it is not possible to change the position of collpased bar by CSS. However, it can still be customized by LayoutRegion.setCmargins(String) like the following.

<borderlayout width="600px" height="400px">
	<east title="East" size="20%" collapsible="true" splittable="true" cmargins="0, 3, 0, 0">
	</east>
</borderlayout>
