[tw5] conditional part of a list widget

I am using something like this;

<$list filter="[tag[Background]tag{!!title}]+[sort[]]">
<h2><$link><$view field="title"/></$link></h2>
<$transclude mode="block" field="text"/>
<hr>
</$list>

but I don’t like the extra hr that it puts on the bottom… Is there a way I can test to see if its not the last item in the list and then hide that using a reveal widget?

You can use the counter attribute of the list widget, like this:

<$list filter=" [tag[Background]tag{!!title}] +[sort[]]" counter="myCounter">
<h2><$link><$view field="title"/></$link></h2>
<$transclude mode="block" field="text"/>
<$list filter={{{ [<myCounter-last>!match[yes]] }}}><hr/></$list>
</$list>

It might not make much of a difference performance-wise, but in my “just in case” mindset, I’d do something like this:

<$list filter=" [tag[Background]tag{!!title}] +[sort[]]" counter="myCounter">
<$list filter="[<myCounter>!match[1]]"><hr></$list>
<h2><$link><$view field="title"/></$link></h2>
<$transclude mode="block" field="text"/>

</$list>

BTW: when viewing my previous reply in Google Groups, ignore the triple tick-marks before and after the TW scripting.

Those triple tick-marks are only there so that the code, when viewed via the Talk.TiddlyWiki discourse forum, does not get mangled.
