Display parent tiddler's name alongside the child

[passingby]

If I have Project tiddlers as parents and Tasks as children tagged by the parent's name:

Project-1

              Task1

              Task2

              Task3

Project-2

             Task4

             Task5

How do I create a list like this:

Task1 - Project1

Task2 - Project1

.....

Task4 - Project2

In other words, when I iterate through the list of Tasks, I wish to display the Project's name alongside. Is it possible? The only link between the project and the task is that the task is tagged with the project's name. So the logic generating the list has to look backwards somehow.

It's certainly possible. Are there some characteristics of the parents? Eg, do they all have titles starting with "Project" or are they tagged "Project"?

Best,

I think you want the tags[] filter operator. How about:

<$list filter="[tag[Task]]">

    <$link to=<<currentTiddler>>/> (part of project <$link to={{{ [all[current]tags[]tag[Project]] }}}/>)

</$list>

This assumes your tasks are tagged Task and your projects are tagged Project...you can replace the tag[Task] and tag[Project] bits in the filters with whatever criteria you need to determine if something is a task or a project.

Thank You! Yes, it works. I have been using TW5 off and on for quite a long, but whenever I come back after some time, I get lost and need help. 

Tiddlywiki is such a unique and wonderful software, but unfortunately, it is like this, at least with me, every time I come back after a gap, there is a learning curve to be climbed up again.
