CSS bindings: How to repeat element and change both attribute & content

[Jeppe Nejsum Madsen]

Hi,

I have a template like this:

<tr class="leasing_company">
<td class="row-labels name">lc name</td>
<td class="values">123</td>
</tr>

I need the tr's to repeat and within the structure, the last td
element to repeat with content but also with a specific class
attribute.

The last bit seems to cause some problems:

I have this:

".name *" #> lc.name.is &
".values *" #> res.segments.map {segment =>
res.filteredResult(lc).avg(segment).toString}

which will handle the td with content, but how do also add a
(calculated) class attribute to the td?

Thanks, works great! I've updated the Wiki with this example and the
"*" selector.....

The CSS binding stuff is both neat and very powerful, but I feel I
lack a good reference as to what is possible (maybe this was the only
one missing from the Wiki, in which case everything is fine :-) The
amount of implicits at work to make this happen makes it less than
trivial to peruse the source....

I think a lot of material for a good reference on CSS Selector Transforms will come from today's training.

I've been keeping the facts up to date here: http://stable.simply.liftweb.net/#sec:CSS-Selector-Transforms

I expect there will be a bunch of CSS Select Transform recipes that make it into Simply Lift.
