Not sure what you mean, but you don’t ‘link’ taxonomies. I’m assuming you’re discussing about your website project and the ‘faceted search’ from the left pane. (Drilling down from State to City or things of that nature), both taxonomies are present and the choice of the first taxonomy ‘filters’ the list for the second choices, so they’ll only show the values that remain. Doing that in a form requires conditional logic to be checked at the form level and would require either a form engine or jQuery/PHP queries to change the values of the select lists based on the value of other fields. It’s outside the scope of our support, unfortunately, as that’s a pretty advanced topic. We usually suggest people use a faceted search to limit the ‘input’ methods and (once someone has filtered the choices down) pass those values over to an input form using Query variables.
And nope, we don’t have any examples of the above or a video, because it’s beyond the scope of what we provide with Pods. That’s forms engine type of stuff and we’re not a forms engine.
You can create a relationship field between taxonomies, but you’d still have to do a significant amount of coding to perform ‘filtering’ where only values from the second taxonomy show that have a value from the prior one, but that would help with the ‘filtering’ of the options or at least making it so you only show values in one taxonomy that have a relationship based on another field value.
You might try StackOverflow.net with your question, but you need to be more specific in what you’re trying to accomplish than what you provided above.
