# How to Use the "Quantity" Feature for Options
### How to Use the "Quantity" Feature in OPTIS
The Quantity feature in OPTIS allows customers to select multiple option values in 1 option.
### How It Works
* **Enabling Quantity**: Check the box in the Quantity column to let customers adjust how many times they want an option.
* **Min/Max Quantity:** Set a minimum and maximum limit to control how many times the total option number can be selected.
* **How It Affects Price Add-Ons:** The final price of a product will increase based on the selected quantity multiplied by the Price Add-On value.
### Example – Selecting Candies for Candy Box
#### **Setup in OPTIS:**
* **Option Name:** Select candies (up to 5)
* **Option Values:** 6 candy options
* Min quantity is 3, and max quantity is 5
This means customers can select up to 5 numbers of candies. For example, 4 black candies and 1 pink candy.
If you add add-on price for those candies, for example, black candy costs 5 and pink candy costs 10. Here is the total price if customers select 20 black candy + 30 pink candy:
* Total price = 5x20 (black) + 10x30 (pink) = 130
### Step by Step Guideline
1. On the Option values, check the Quantity box for the option.
2. On the section “Quantity Settings”, define the minimum and maximum quantity customers can select
***Note***: The Min/Max Quantity setting applies to the total quantity of the option value, not individual selections.
3. On the section "Price add-on", enter an extra charge per unit (if needed)
