[Javascript] Dynamically Adding & Removing Items Between a DIV

[List_Mail_Att]

I have search Goggle and have gone to all types of
JavaScript sites but can't find an answer.

Can someone lead me in the right direction?  Please.

<Div id="xxx"]

    I want to be able to TOTALLY REMOVE ALL ITEMS 
          (not just Hide\Show) 
    and
    I want to be able to add ITEMS (i.e. Tables, etc.)

<\Div]



Thanks,
Gene
