[ZPT] CSS relativity

[Arnar Lundesgaard]

Not certain if this is what you want to do, but you get an idea.

Below are three examples:
  <span tal:define=3D"test1 python: 1; test2 python: 0"
        tal:attributes=3D"class python: test1 and 'nav'
                                   or test2 and 'herenav'
                                   or 'subnav'">
    Example One
  </span>

  <span tal:define=3D"test1 python: 0; test2 python: 1"
        tal:attributes=3D"class python: test1 and 'nav'
                                   or test2 and 'herenav'
                                   or 'subnav'">
    Example Two
  </span>

  <span tal:define=3D"test1 python: 0; test2 python: 0"
        tal:attributes=3D"class python: test1 and 'nav'
                                   or test2 and 'herenav'
                                   or 'subnav'">
    Example Three
  </span>

Which gives:
  <span class=3D"nav">One</span>
  <span class=3D"herenav">Two</span>
  <span class=3D"subnav">Three</span>


Your test might be written something like this.
This is not tested, so you will have to work out
the details yourself though.

<tal:loop repeat=3D"item python:container.objectValues(['Folder'])">
  <span tal:define=3D"test1 python: item.title in request.URL;
                    test2 python: request.here in request.URL;
                    nav   python: test1 and 'nav'
                               or test2 and 'herenav'
                               or 'subnav'"
        tal:attributes=3D"class nav">
    <a href=3D"dummylink" class=3D"dummyclass"
       tal:attributes=3D"href item/absolute_url; class nav">
       tal:content=3D"item/title"
      Dummy linkcontent
    </a>
  </span>
</tal:loop>
