I have over 7,000 downloadable documents which have attributes of: Age, Type, Subjects, and Topics within Subjects. I need to filter the search across these attributes in a tidy fashion.
I have created one field for 'Subjects' which is a drop-down list.
I have another field which is a drop-down list which are 'Topics' within certain Subjects. I need to relate these lists in Search so that for example, if Subject 'Maths' is selected then the 'Topics' drop-down offers only Maths Topics, and if Subject 'English' is selected then it offers only English Topics. This is necessary to filter the search across the large number of documents with about 70 different Topics within 20 Subjects. The Topic lists could be in separate drop-down fields if required - i.e. one for each Subject.
Please could you help us achieve this?

This feature is quite complex.
In your case, you can try to use javascript to filter the dropdown, however we can not help on this.
If you don't know javascript, you can hire a freelancer to do it for you.
