This is a simple module that automatically selects parent terms in a taxonomy.
For instance, imagine a "Geography" taxonomy having all continents, countries and cities in a tree structure. Users are then asked to tag a piece of content with this taxonomy. Suppose a user tags a piece of content with "Berlin". Using the normal Backdrop taxonomy system, this would be the only term applied in our tree. The content would not be able to be found under "Germany" or "Europe". What this little module does is simply make sure that these parent terms are also selected at the time a piece of content is saved.
By selecting the "Geography" taxonomy in the module administration screens, a user can ensure that these parent terms are selected and hierarchical taxonomies become more powerful.
If any vocabularies have lineage set, we check entities when they are saved to see if they have fields referring to these vocabularies. If so, we automatically select all parent terms of manually selected terms.
Note that this does not override the maximum number of terms selectable in a field. If for a given field, content creators are only allowed to select one term, this module will not be able to set any parent terms in that field.
This module should work with any Backdrop language / i18n / localization strategy. This module will only set parents on the terms in the language that was just changed / edited. That means in a multilingual field with terms selectable independently for each language, if you change which French taxonomy terms are selected, only the French terms will be processed to select parents, not the English terms on the same field. This follows the principle of least surprise.
