I have a struts2 web application with tiles.
I need to make header, sidebar and footer as static, ie. stay constant at their position on screen.
An internal scroll bar for body part is needed.
In total I want to create pages with static header, sidebar and footer and content(body) part only moving with the help of an internal scroll bar.
Tiles is basically a view layer framework based on
Composite View design pattern.Purpose of this pattern is to separate pages into reusable pieces so that we can combine them as per the layout.So your requirement is more towards designing which is case of
CSS/HTML.Tiles will only help to combine your different pieces together and come up with an aggregation any HTML/CSS changes you have to do in respected HTML piece.
