# Hoppers
## Introduction
Our hoppers plugin allows you to do many things a normal hopper can’t, such as auto-crafting, block breaking, super suction, faster item travel, hopper linking, easier filtering systems, and auto-selling. These hoppers have 7 different levels, which increase the radius of suction, amount of links you can use, and unlock new features.
## Rank Information
### Rank 13
When you reach rank 13, you will have access to the hopper GUI. You can open it by left-clicking your hopper.
### Rank 16
At rank 16, you will unlock the ability to "upgrade" your hoppers to access additional features.
### Rank 17
When you reach rank 17, you will be able to use filters in your hoppers.

## Filtering System
The section between the white stained glass blocks is the whitelist. It allows the items to pass through the hopper.
The section between the black stained glass blocks is the blacklist. Items placed here will not be able to pass through the hopper.
The section between the barriers is the disposal. Items placed here will be disposed of.
If the hopper is linked to one or more other hoppers, the items in the whitelist will go through, the blacklisted items will be sent to the linked hopper(s), and the items in the disposal section will be removed.
## Hopper Linking
Open the hopper GUI and left-click the "link" option. You will then need to left-click on a container, then back on the hopper in order to create the link. Once you complete these steps, any items passing through that hopper will be sent to the hopper. Make sure that the bottom of the hopper isn't touching anything else, otherwise, the hopper will not send items to the linked container.
You can set up hopper poles to extend the range of the hoppers, so you can have wireless networks around the place going into a single hopper. Making a storage system will not require much to manage.
## Auto-Selling
To enable the auto-sell feature, you will have to open the hopper’s GUI and click the sunflower on the bottom. This will enable the auto sell, you can also toggle the notifications by right-clicking the sunflower. You can shift-click the sunflower to open the auto selling filter. This allows you to auto sell specific items that pass through, and also have items travel through the hopper.
Just like the normal filtration system, the auto selling filter has the whitelist and the blacklist. The whitelisted items get sold automatically while the blacklist ignores the auto-sell and travels through the hopper to another container.
## Suction
Open up the hopper’s GUI and click on the cauldron. This will enable the hopper’s suction feature. Depending on the hopper’s level, you will have different suction levels, the max is a 3 block radius. You can right-click the cauldron to set the different radiuses of suction to your needs.
