It seems that you are a hobbyist wanted to make something on the web and you find wordpress as a platform since in the wordpress has a template layout design. What you wanted is kinda complex for you to make at the moment but if you wanted, you can learn it. For the design learn HTML and CSS, while for the filter use Javascript. Even though I wanted to make the code for you, it is best that you try to make it with AI so you are able to tweak the design base on what you wanted.
