Trying lessening the amount of functions i need to

I am trying to set the state of size chosen with a function but i have 20 sizes and do not want to repeat a function 20 times is there a way to lessen the code? Is there a way to check and see if the state change matches the props clicked on? 1 when they click the button set the state to the props of the element clicked using one function.

Why not simply make the sizes an array so you can loop over them?

// In your object instead of having multiple sizes keys separately,
// have a single property called sizes
{
    id: 6.97,
    title: "Adidas Yeezy Boost 350 V2 Glow",
    img: "img/product-6.97.png",
    img2: "img/product-6.97-1.png",
    img3: "img/product-6.97-2.png",
    img4: "img/product-6.97-3.png",
    price: 800,
    info: "Adidas Yeezy Boost 350 V2 Glow",
    inCart: false,
    count: 0,
    total: 0,
    sizes:["4", "4.5", "6", "7", /*and the rest of the values*/],
    luxury:
      "All Luxuryitems are inspected to verify authenticity (Sizes above 14 may cost more)",
    category: "Mens Shoes"
  },

//Then you could simply do something like this 
{this.props.yourObjectName.sizes.map((size, index)=> {
   return (
      <DropdownItem className="bg-info" key={index}>{size}</DropdownItem>
    )

})
