TYPO3 EXT: News system, Key: news - Gridview. - typo3

Question

I'm running TYPO3 v. 6.1 FLUID/EXTBASE.
With the extension: News system, Key: news.
On the list.html page that show all the news, I can add UL/LI layout, if I in setup have selected to show 6 news/site.
Is it then possible in the list.html page to tell it that:
LI 1 need style
style="position: absolute; left: 0px; top: 0px; height: 258px; transform: translate(0px, 0px);"
LI 2 need style
style="position: absolute; left: 0px; top: 0px; height: 258px; transform: translate(279px, 0px);"
LI 3 need style
style="position: absolute; left: 0px; top: 0px; height: 258px; transform: translate(558px, 0px);"
... to LI 6, all the li don't have a number, but here I ref. to the 6 news/site i have set in the setup.
so i can make a gridview of 6 news in 2 rows, with 3 columns ?

Answer 1

You could use iteration in the each-viewhelper like
<f:for each="{news}" as="newsItem" iteration="iterator">
<f:if condition="{iterator.index} == 1">...</f:if>
<li class="first-item"></li>
</f:if>
<f:if condition="{iterator.index} == 2">...</f:if>
<li class="second-item"></li>
</f:if>
</f:for>
but you have to add this conditions to all items. else you could use the cycle-viewhelper to define columns like this:
<f:for each="{news}" as="newsItem">
<f:cycle values="{0: 1, 1: 2, 2: 3}" as="cycle">
<f:if condition="{cycle} == 1">...</f:if>
<li class="col-1"></li>
</f:if>
<f:if condition="{cycle} == 2">...</f:if>
<li class="col-2"></li>
</f:if>
<f:if condition="{cycle} == 2">...</f:if>
<li class="col-2"></li>
</f:if>
</f:cycle>
</f:for>
here you just have to add conditions to each column.
i would add just classes by condition, not the whole li-tag but the code above is nicer to read i think.
<f:for each="{news}" as="newsItem" iteration="iterator">
<li class="{f:if(condition: "{iterator.index} == 1", then: 'first-class')} {f:if(condition: "{iterator.index} == 2", then: 'second-class')}">
</li>
</f:for>

Execution start with 0 so it will be like...
<f:for each="{news}" as="newsItem" iteration="iterator">
<f:if condition="{iterator.index} == 0">...</f:if>
<li class="first-item"></li>
</f:if>
<f:if condition="{iterator.index} == 1">...</f:if>
<li class="second-item"></li>
</f:if>
</f:for>
