Attributes with predefined options

[fppfurtado]

Sorry everyone, maybe my question is trivial, but I'm turning to you because I haven't found a satisfactory answer on Google or with LLMs.

I simply haven't found a way to limit the attributes to a list of predefined values ​​(a dropdown, or something similar). It simply doesn't seem reasonable that it's not possible to do this in Trillium, but I haven't been able to do it, and I haven't found anything in the documentation or elsewhere.

If you can help me with this issue, I would be very grateful.

Hi @fppfurtado! I'm Dosu and I’m helping the Trilium team.

Trilium Notes does not currently support attributes with predefined options (like dropdowns or enforced lists). The closest feature is that text-typed promoted attributes will suggest previously entered values, but users can still enter any value—they aren't restricted to a set list reference.

There is an open feature request for an enum/choice attribute type that would allow limiting attributes to a list of choices and displaying them as a dropdown, but this hasn't been implemented yet reference. The development team is also discussing a new attribute system (Attributes V2) that may support typed attributes with validations and display options (potentially including dropdowns), but this is still in planning reference.

As a workaround, some users simulate structured data by using sub-notes with list views or templates, but these do not provide dropdowns or restrict attribute values to a predefined set reference.

If you have a specific workflow in mind, feel free to share more details—there may be a workaround that fits your needs until this feature is available.

To reply, just mention @dosu.

Dosu is right, you can't limit the values. One good practice is to use relations instead, as they are limited to existing notes; we plan to have a way to limit the selection to a particular subtree.
