Woocommerce Attribute Custom Display/ Functionality

Hello,

I’m currently setting up a new Woocommerce site and am relying heavily on the product attributes to create a search/ filter functionality for users.

We want users to search based on
1) manufacturer
2) model (restricted by manufacturer selected)
3) series (restricted by manufacturer and model selected)
4) Product category

Customization One: As product categories by default don’t show/ hide available options by attribute selected, we are doing this through the attribute area. With any sub categories, however, it labels them “cat 1, sub cat1”, “cat 1, sub cat2” etc.

Rather than this I’m trying to get them to display as an intended line without the main cat title before it

Customization Two: With the attributes 1,2, and 3 above we want them to be restricted based on what the user selects (i.e. if they select manufacturer one, they then only see model 1, 4, and 6). Woocommerce attributes already does this. The issue is that some products may be related to manufacturer 1 and 2. therefore, when a user selects manufacturer 1 it will now have the models from both manufacturer 1 and 2 that are on that product. We want some way to restrict these. One idea is to have one attribute and then list models as sub attributes to the manufacturer, however these would not display as separate drop downs.

Does anyone have a solution to this or something that could work for either one of these requirements

Thanks
