Thanks for contacting us and choosing our product!
Now we are using isotope layout: https://isotope.metafizzy.co/
and don’t have filter when hover for sub category as you want.
We’ll notice and research to added it later.
Can you describe more detail about your requirement.
– On desktop: hover category show sub category (how many sub level) and filter will only show video in sub category?
– On Mobile: ….
After clear all your requirement, we’ll check again and feedback. Please note you need to pay 50% first before we do customize work.
Currently we are so busy and can’t do it immediately.
You can pay 50% (50$) via Paypal email firstname.lastname@example.org . We’ll do it at the weekend.
After we finished you can pay 50% remain.
However clear more about design.
When hover on Level 0 it will show Level 1. After selected Level 1 to Filter It will still active on Level 0 and when you hover it active on Level 1 too.
Or the text of Level 1 will replace the text of Level 0.
Please more clear about requirement. So we can do exactly as you want.
We got your payment but we are so busy in this week and maybe can finish your custom work in Tuesday of next week or maybe sooner.
If you agree with this we’ll do it.
If you don’t agree maybe we’ll refund for you.
Also your requirement is more detail and we need much time than we think before.
