Consider the following usecase: Introduced in v5.1.16
There is a field named: rank, which can hold different values eg: species.
Answer:
The idea is now: We dynamically create the stylesheet. The style-sheet can look like this:
title: myStyles
tags: $:/tags/Stylesheet
<$list filter="[rank[species]]">
[data-tiddler-title^="<$view field=title/>"] .tc-tiddler-body {
column-count: 2;
}
</$list> This creates a CSS rule for every tiddler-title, that has a field rank and value species.
