Hello,
I find that people experiences lots of problems when using nested list. The
main problem is losing the reference to the current tiddler. Many people
solves this using the set widget:
<$set name="parent" value=<<currentTiddler>>>
<$list filter="[tag[sometag]]">
I'm on <<parent>>. Item from the list <<currentTiddler>>
</$list>
</$set>
I used and saw even more twisted configurations. If the problem is losing
the reference to parent, then the list widget has a feature that can help
you giving better names to items on the list:
<$list filter="[tag[sometag]]" variable="item">
Now I can use any kind of reference to parent: {{!!title}}, <
<currentTiddler>>. And the list items are more obvious: <<item>>
</$list>
You can go as deep as you want
<$list filter="[tag[sometag]]" variable="item">
<$list filter="[tag<item>]" variable="subItem">
I can still referencing parent {{!!title}}. Items: <<item>> <<subItem>>
</$list>
</$list>
You can use the variables at any level and make any kind of configuration
you want. Everything will keep neat and clear:
<$list filter="[tag[sometag]]" variable="item">
Here I am on the <<currentTiddler>> listing subItems of <<item>>
<$list filter="[tag<item>]" variable="subItem">
I can still referencing parent {{!!title}}. Items: <<item>> <<subItem>>
</$list>
</$list>
Pretty nice, clear, powerful and flexible I think.
