Building taxonomy Selector I'm building a classified website, on which users can create ads using the custom content type I've created. Each ad has a category field which a reference to a multilevel taxonomy, and uses the  hierarchical select field type.

When a user creates an ad/classified, I'd like the UI to first ask the user to choose from the the top-level terms of the taxonomy, then from the child terms of what is selected, then the child terms of that, so on so forth.

Here's an example of what I'm trying to achieve:


I've already tried using Conditional Fields with Hierarchical Select, and Simple Hierarchical Select but neither have worked out so far. I'm trying to create something that's user friendly.

Any help is appreciated.
You can try with Hierarchical Select module.


  This module defines the "hierarchical_select" form element, which is a greatly enhanced way for letting the user select items in a hierarchy.
