如何在reactstrap Dropdown中设置所选项目？

有下拉列表的示例:https://reactstrap.github.io/components/dropdowns/

当我在下拉列表中选择项目时,它不会显示.

*******************工作方案*****************************

import React from "react";
import {ButtonDropdown, DropdownItem, DropdownMenu, DropdownToggle} from "reactstrap";
import superagent from "superagent";

class BootstrapSelect extends React.Component {

    constructor(props) {
        super(props);

        this.toggle = this.toggle.bind(this);
        this.changeValue = this.changeValue.bind(this);
        this.state = {
            actions: [],
            dropDownValue: 'Select action',
            dropdownOpen: false
        };
    }

    toggle(event) {

        this.setState({
            dropdownOpen: !this.state.dropdownOpen
        });
    }

    changeValue(e) {
        this.setState({dropDownValue: e.currentTarget.textContent});
        let id = e.currentTarget.getAttribute("id");
        console.log(id);
    }


    componentDidMount() {
        superagent
            .get('/getActions')
            .type('application/json; charset=utf-8')
            .end(function (err, res) {
                console.log(res.body);
                this.setState({actions: res.body});
            }.bind(this)); …

我可以通过以下方式获取 vue js 2 中的组件名称：this.$options.name。如何在 vue js 3 中获取它？

谢谢。

我添加到索尔索引:"美国".当我搜索"美国"时,没有结果.

如何配置schema.xml以获得结果？

目前的配置:
