Hi. I want to use your codes for my wordpress site. I supposed dd.php, main.php and mainck are all i need for the ajax version of the dropdown.

But where should i put these files? I don't need the config.php since i'm using global $wpdb. THe javascript i put in my header. The Dropdowns i put in my page. But how about the dd.php?

Greetings. This solution has worked great for 2 years; however, when there are more than 100 records in a given category, that category does not get populated in the 2nd dropdownlist. Do you have any recommendations? Urgently needed and great work!

In the table structure you have Type for cat_id and subcat_id like this

subcat_id int(3)
cat_id(2)

Increase the number by one

subcat_id(4)
cat_id(3)

That will solve the problem. You should login to your database ( phpmyadmin ) and change / edit the each field structure.

You are using wrong script, try to use the script with Ajax. The page should not reload so your form data will remain.
