Javascript 我们如何将react Dnd正确地用于同一项可以多次拖动并附加到react状态数组

我使用react dnd拖拽和放下物品。。 左侧我有一个项目列表，如文本框、复选框、单选按钮等。 当我开始拖动一个文本框并将其放入中间的容器中时，效果很好。 例如，我每滴都会增加我的状态id 状态：{id:“text1”，名称：} 当我再次拖动同一个文本框并将其放入中间容器时，我的状态会得到重复的值，如 例如，state=[{id:“text2”，name:}，{id:“text2”，name:“}]

当我多次删除单个项目时所需的实际输出

例如，state=[{id:“text1”，name:”“}，{id:“text2”，name:”“}，{id:“text3”，name:”“}]诸如此类

我已经搜索了所有react dnd的例子…但是没有一个能帮我。。。请帮帮我，伙计

DummyData.tsx

import type from '../assets/images/type.png'
import paragraph from '../assets/images/paragraph.png'
import dropDownList from '../assets/images/drop-down-list.png'
import text from '../assets/images/text.png'
import checkbox from '../assets/images/checkbox.png'
import radioButton from '../assets/images/radio-button.png'
export const Controls = [
    {
        id: "text", label: "Text Field", fieldClass: "Text", category: "basic", image: type,
        height: 30, width: 200, placeholder: "Enter your name", readOnly: false, disabled: false, required: false
    }
    , {
        id: "textArea", label: "Text Area", fieldClass: "TextArea", category: "basic", image: text
    }
    , {
        id: "dropdown", label: "Dropdown", fieldClass: "Select", category: "basic", image: dropDownList
    }
    , {
        id: "radio", label: "Radio", fieldClass: "Radio", category: "basic", image: radioButton
    }
    , {
        id: "checkbox", label: "Checkbox", fieldClass: "CheckBox", category: "basic", image: checkbox
    }
    , {
        id: "paragraph", label: "Paragraph", fieldClass: "Paragraph", category: "basic", image: paragraph
    }
]

我想要什么
