Alessandro Cipriani	Monday 19 April 2004 2:23:03 am hi all i've this problem: the user of my site will be categorized with two parameters, the second linked to the first in this way (either are select attribute): cat1 -subcat11 -subcat21 -subcat31 cat2 -subcat21 -subcat22 and so on in such an organization i'd like to avoid any error (like to have a customer of category 1 and subcategory 21) during the user registration. the simplest way i thought was to write a javascript that loads only the appropriate values on the 2nd select one a choice on the first one is made. but i've problem with javascript function and i don't know if it's the right choice. is there some built in mechanism to solve this problem? best regards alessandro

Gunnstein Lye	Tuesday 20 April 2004 12:40:48 am You can of course have two combo boxes, but you only need to store the second one. You can use the first one only to choose the right content for the second one (with javascript). I suggest you use alternative attribute views, for instance: (in register.tpl) {attribute_edit_gui view="myspecialjavascript" attribute=$myattributelist.myattribute} Now, create your special attribute in mydesign/content/datatype/edit/myspecialjavascript/ezselection.tpl (if your attribute is an ezselection, of course.) This way you don't have to have the same template for all attributes of the same type.
