I have a set of notes with tags of the form Tag/Subtag. I’m preparing a Bases table view and would love to only see the associated ‘Subtag’ in a “tags” column.
I’ve searched the forum and found some custom CSS for dataview, but am unsure if this can be incorporated into Bases at present.
Create a formula e.g.: list(tags)[0].split("/")[1]
I haven’t tested this yet but WhiteNoise mentioned
file.hasTag()is the solution regarding supporting nested tags in bases.
You’ll be able to search for parent tag in frontmatter-only tags with
tags.filter(value.startsWith('parent'))
Is there any way this can be expanded to handle items with more than 1 tag? I noticed it works great if something only has Tag/Subtag, but if it has Tag/Subtag and another Tag/Subtag, only the first result is returned.
As far as I can tell, this is useful for applying a Filter but I am trying to display the relevant tags as a Property so I’m not sure how this helps? I might be missing something though!
There are a lot of possible variations depending on your setup and what you want to display. This formula drops the first parent of all the tags:
tags.map(value.split("/").slice(1)).flat()
You can use join() to add a symbol of your choice between the child tags, such as:
tags.map(value.split("/").slice(1)).join(", ")
Or do a variation on those to get the display you want.
This is perfect, thank you so much! I haven’t used JavaScript much, so didn’t know the proper syntax to chain the formulas together.
