Inconsistent behavior when adding new hierarchical tags in Digikam

Question

Whenever I create a new hierarchical tag in Digikam (right-mouse click on image -> Assign Tag -> Add New Tag) then all hierarchy levels are applied to the image. For instance, if I have the hierarchy Tag 1 / Tag 2 and add a new tag Tag 1 / Tag 2 / Tag 3 to an image, then all tags Tag 1 / Tag 2 / Tag 3 are applied to the image.

In contrast, when I add an existing hierarchical tag to an image, then only the bottom level is applied. Picking the example from above up, when I add Tag 3 to an existing image, then only Tag 3 is applied but not Tag 1 / Tag 2.

I find this a bit inconsistent, as I now have some images with the full hierarchy and some with the bottom level only.

Is there some way to standardize the behavior of Digikam?

Answer 1

If I understood your question correctly, it might be the Toggle Auto setting of DigiKam.

With the Captions pane open, right-click on any one of the tags listed, go down to Toggle Auto and choose Parents.

Now when you check off a child tag, all of the other tags up the hierarchy also get checked.
