[TYPO3-english] How to hide objects in typoscript?

[Michael de Jong]

Hi people,

I am pretty new to the whole typoscript language, but i have this problem i can't seem to firgure out... Is there a way to hide elements in typoscript that is something like the php if / else ? So for instance:

If pageID = 1,2,3 then show object, else show something else?

I hope someone can help me with this, because i have been at it for a couple of days now xD

Thanks,
Michael de Jong
