With Facets module/search API, I have a checkbox filter where I need to merge some value.
Exemple: vocabulary = color term = light red term = dark red term = light blue term = dark blue
In this case i have 4 checkbox.
My checkbox should look like this
vocabulary = color term = red term = blue
And When i tick Red it list all content tagged with dark red and light red And When i tick blue it list all content tagged with dark blue and light blue
thus the parent term will not be a used value in the filtered content, but only the child value will filter the content.
Is it possible to do that with taxonomy hierachy option in the facets?
