Filters Frontend

[JonathanWuz]

My feature was originally a filter system, but I have since changed it to a marketplace where businesses can buy and sell items. I have this in a replit format right now and plan to add this to the group repository this week. I will also work on creating more values in our database or a separate database for my feature's necessary components.
Here is where you can enter items you want to sell:

Here is where you can purchase items:
