How do you display a custom field for a specific type?

How do you display a custom field for a specific type?

I have a field that is will only display on the form's template if it is assinged to the parent category content type.


I have:
===============================
Main category (contentType= Maincat)
-> Sub Category1 (contentType= cat1)
-> Sub Category2 (contentYype= cat2)


I configured:
- custom field1 gets assigned to contentType cat1
- custom field2 gets assigned to contentType cat2.


The custom fields will not display in the entry forms unless I include "Maincat". But if I do this then both field display which wan I'm trying to make the field category specific.

How do I get a custom field to only display for a specific category and content type.



I created a field. I assigned it to a type. The type is tied to its own template.


Thanks

Hello

-- use jQuery to bind at the onChange event on form element with HTML tag ID: '#jform_catid' which is the form element of main category

and the code attached to the onChange event will check which main category is selected and decide to hide+disable the form field or show+enable the form field

Regards

Thanks I will give it a try.

But for clarification, is this happening because only one template can be assigned to the content type?

thanks

Hello

we are taking about item form, so why is the template used in item viewing , related to this discussion ?

I see, the Item layout is only for details view. I thought there was a way to assign custom form template.
