如何解决使用react-bootstrap组件和react-select菜单的z-index问题？

Question

我正在使用react-select和react-bootstrap，遇到了以下问题。我创建了一个bootstrap卡片，在其中放置了一个react-select组件，但问题是当我打开react-select菜单时，它没有完全显示出来。我尝试过更改z-index值和将位置设置为relative，但仍然没有改变。

这是我的问题截图：Image

import React from "react";
import Form from "react-bootstrap/Form";
import Row from "react-bootstrap/Row";
import Col from "react-bootstrap/Col";
import MonthSelect from "../../../selects/MonthSelect";

import Container from "react-bootstrap/Container";
import Accordion from "react-bootstrap/Accordion";
import Card from "react-bootstrap/Card";
import Button from "react-bootstrap/Button";

const FeeSearch = props => {
  const { register } = props;

  return (
    <>
      <Accordion>
        <Card border="secondary">
          <Card.Header style={{ padding: "5px" }}>
            <Accordion.Toggle as={Button} variant="link">
              <h6>Búsqueda</h6>
            </Accordion.Toggle>
          </Card.Header>
          <Accordion.Collapse in={true}>
            <Card.Body>
              <Container fluid>
                <Form.Group>
                  <Row>
                    <Col xs={3}>
                      <Form.Label>Mes</Form.Label>
                      <MonthSelect register={register} />
                    </Col>
                  </Row>
                </Form.Group>
              </Container>
            </Card.Body>
          </Accordion.Collapse>
        </Card>
      </Accordion>
    </>
  );
};

export default FeeSearch;

使用menuPortalTarget属性将您的react-select渲染到文档的根部。问题在于，您的react-select被渲染到具有overflow: hidden的特定堆叠上下文中。通过渲染到，您可以确保没有包装上下文截断您的内容：

<Select menuPortalTarget={document.body} />
