I Am using multiselect dropdown, what i want is whatever i've selected in dropdown to send it to the server by calling an api which contains query param to accomodate these dropdown result. I have made an array of selected items. Array(3) [ "IphoneXR", "Nokia", "Samsung" ] I want this array to get pass to below url like this: http://localhost:8080/details?dropdown=IphoneXR,Nokia,Samsung. With my approach i am ending up with this: http://localhost:8080/details?dropdown[]=IphoneXR&dropdown[]=Nokia. I am not sure why dropdown[] is coming twice. Can anyone please help me with it

Convert the array into string and pass the value in query param.
multiSelectHandler = (option) => {
const details = option.selectedItems;
const stringData = details.map(({value}) => `${value}`).join(',');
console.log(stringData);
};
Array: Details: Output in console
0: Object { value: "Iphone", label: "Iphone" }
1: Object { value: "Samsung", label: "Samsung"}
After converting into string:Output in console, Iphone,Samsung
Now pass this stringData in queryparam

If you are passing it directly to a url via the form actions it will sent it in the url as this: index.html?cars=saab&cars=opel&cars=audi
Try handling the form via js like this How handle multiple select form in ReactJS
