About sync properties

Hi,
I'd like to know if is possible to link different tags in search mod.

For example:

I've CATEGORIES and SUB-CATEGORIES

In Categories there are CARS, BIKE, BUS. In subcategories instead I've SPIDER, SPORT, ELECTRICAL, 9SIT, 18SIT and so on...

Obviously some subcategories are only for some categories (es. 9SIT and 18SIT are only for BUS Category) so my question is:

Is possible to get into module this function: if I choose Category BUS in the following Subcategory it's shown me only 9SIT and 18SIT and no other subcategories...?

Thank you

You could have different search modules showing different custom properties.
You can see an example on our demo site.
On the homepage ( solidsystem.it/demo31/ ) you see a search module with all custom properties.
On the wine page ( solidsystem.it/demo31/index.php/en/wine ) you have another search module the searches only within the wine category and sub-categories.

To refer to your example, you should add a "Search BUS" cpsearch module, whose search scope is resctricted to BUS categories.
You'll also need to assign custom properties that are relevant only to buses, to the "Search BUS" search module.
