Hi,

I want to make something like this:

I have a List/Menu populated from a database table named categories.If an item of List/Menu have sub categories then  the subList/Menu must appear in the page(in a conditional region) ,else not appear.The subList/Menu is populated from a database table named subcategories .The subcategories have a foreign key which name is tha same with the primary key of table categories:

Categories (id_cat,name)

subcategories(id_sub,name,id_cat)

Any suggestion   ?

I suggest mentioning the server-side scripting language you plan on using.

The basic process involves creating a recordset for the categories then create another filtered recordset where URL parameter = id. in your menu have links to categories contain a URL parameter id which is passed when clicked to show the sub categories based on the filtered recordset checking against the URL parameter id. Nest your conditional region if URL parameter id isset then show the subcategory else don't show anything.

You can also use a dependent drop-down with spry. Exmple provided. View and study source code.
