Create an eventhandler in your MainMenu component which fires on select and
gives the selected menuitem as context.
For example
class MainMenu
@Inject
private SideMenu sideMenu;
Object onActionFromYourMenu(String context)
{
sideMenu.setSelectedMainMenuItem(context);
return null;
}
class SideMenu
@Property
@Persist
private String selectedMainMenuItem;
@Inject
private Block whateverBlock;
@Property
@Persist
private Block displayBlock;
Object setupRender()
{
if(selectedMainMenuItem.equals("whatever")
displayBlock = whateverBlock;
...
return null;
}
SideMenu.tml
<div class="sidemenu">
<t:delegate to="displayBlock"/>
</div>
<t:block t:id = "whateverBlock">
<ul>
<li>Whatver has to be done</li>
<ul>
</t:block>
