Add 'other' option to checkbox list

Is there a way to add a manual “other” field at the bottom of a checkbox list for attributes? I’d like vendors to be able to add additional items to their list other than the choices I have provided.

Unfortunately, there is no such possibility in the current version. As a possible solution please try to use the HivePress Tags extension Tags - Allow users to set listing tags | HivePress Extensions which gives the possibility to vendors to choose tags that are added by you as website admin or to add their own tags for each listing
