I have created a taxonomy vocabulary called Cars makes and models with a structure similar to this:
-Car Make
----Car model
-----------Year
I want to give the customer, options to sort them in a View , like many cars sites do: a customer choose first the Car make, and automatically models from this make shows in a second level list. But I want also to use this functionality in the (add content )page, so when customer try to sell a car, he will not need to scroll a very large list with makes and models in the same field. I cannot use Hierarchical Select. As many topics in this site suggest, because it doesn’t work for exposed filters in Views, with Drupal 7: http://drupal.org/node/1170192
I have spent hours and days, trying to fix this issue without any success, my options are very limited:
- Turn back to Drupal 6, Just to use HS with Views exposed filters. (not a brilliant idea)
Use other CMS like Joomla, in fact there is many Joomla plugins offering this functionality: http://extensions.joomla.org/extensions/vertical-markets/vehicles , but then I will lose all the power of Drupal taxonomy.
Add autocomplete functionality to the views filter and Use Autocomplete term widget , in the (create content page) , but this is not very user-friendly method for no experimented users. More, Autocomplete term widget will allow the creation of new terms, and I do not want users to accidentally create new terms when they enter an incorrect model or make in the field. Maybe I can correct this using Content Taxonomy module(http://drupal.org/project/content_taxonomy), which can deny the creation of new terms. But this is not a global solution to my problem.
Is there a module or any JavaScript or PHP snippet to fix this ?
