Removing Options when Filtering via Specification Attributes

When selecting a Specification Attribute to filter by in Nop Ajax Filters, it "grays out" options that are not possible under all other Specification Attributes. How can I modify the code to "gray out" options that are not available under the same Specification Attribute?

To add further detail:  
•  I have 10 products that have HDMI inputs
•  I have 4 products that have SDI inputs
•  I have 2 products that have both HDMI AND SDI inputs.
When I check HDMI and SDI, there should be only 2 products remaining representing the AND condition.  What actually happens in this example is that I get 12 results, which represents the OR condition.

How do I fix this

Hi,

Would it be possible to share a link to your filters so that we can get a better idea of your product and specificaitons setup?

Thanks

Any additional feedback from anyone?  Please?

Hi selnicmf,

This is the way the Ajax Filters work. When the options are within a group then you can select all of them. So if you want to have AND between the options, you need to separate them in different groups i.e HDMI Inputs group and SDI Inputs group rather than having a single INPUTS group.

Hope this helps!

Thanks
