Hello,

here is a part of the documentation, if you have more questions, i will gladly answer them :

Cascading fields

Cascading fields are a special type of field available with AdsManager Silver or Gold pack. This allows for the content of fields to depend on another. For example: you have two dropdown lists where users select a country and then a city. With cascading, when the user selects a country the list of available cities changes to match the selected country.

First, you need to select the cascade type field to display its options.

In the options of the field, you need to specify the name of the parent field.

You can choose to use Ajax to load the data.
If you choose yes, the child dropbox field will be displayed without a page reload, otherwise, the page will be reloaded.

Then, you need to set the values of the field to cascade on, you can fill these values the same way as you would for the parent field.

When users select a value of the parent field, all children who cascade on that value will be displayed.

Hello,

The parent field can be a single drop box and the child field must be a cascade field.

When you create the parent field, you need to fill the list of options in the field edition.

Then in the child field, you need to fill the textfield 'Parent field name' with the name of the parent field.

After that, fill the list of option and indicate for each option what is the parent field value of will display the option.

You can see an working example on demo.joomprod.com/ . Use the demo account to connect on the administrator and check the field of adsManager.

What is the problem exactly ?

The cascade field is never displayed or it shows the wrong value ?
