Hi Luis,
There's a freemarker builtin that you should be able to use:
http://freemarker.sourceforge.net/docs/ref_builtins_sequence.html#ref_builtin_sort_by
Putting it all together, it might look something like this:
<#list rest("/boards/style/blog/nested").boards.board?sort_by("title") as board>
<#-- Do stuff -->
</#list>
I hope this helps!
- Thanks Adam. Looks like it's working
Hi Adam,
The built in is working just fine. I'm now facing a REST API call issue.
I'm trying to retrieve certain Community's blog list with
<#assign global_blogsCount = rest('boards/style/blog/nested/count').value/>
However, when I try to use this value for a very simple calculation such as
<#assign leftColumnEnd = (global_blogsCount/2) />
I get the following error.
Expression global_blogsCount is not numerical
Could you please advice?
Gracias,
Luis
As far as freemarker is concerned, the value you're getting back is a string. So if you want to use it as a number, you need to convert it. There's a "number" built-in that can be used with strings. For example:
<#assign global_blogsCount = rest('boards/style/blog/nested/count').value?number />In case you're curious, you can find a full listing of the available freemarker built-ins here:

I hope this helps!

Thanks Adam,
That worked out the issue. Could you please point out what's wrong on this snippet?
<#if (global_blogsCount % 2) == 1)>
<#assign leftColumnEnd = (leftColumnEnd?int) + 1 />
<#/if>
<#list global_blogs.board?sort_by("title") as blog>
<#if gblogIdx != 0>
<#if (gblogIdx == (leftColumnEnd + 1) >
<#assign blogMenuContentAlpha = blogMenuContentAlpha + '</div><div class="hp-sub-nav-row blog-list-right">' />
<#/if>
</#if>
<#assign blogMenuContentAlpha = blogMenuContentAlpha + '<div class="hp-nav-col"><ul><li><a href="${blog.@view_href}">${blog.title}</a></li></ul></div>' /> <#assign gblogIdx = gblogIdx + 1 />
</#list>Lines in bold are breaking my code
Gracias,
Luis
