Add the readOnly prop on an input to prevent modification of the input's value. Read-only inputs appear lighter (just like disabled inputs), but retain the standard cursor.,Add the disabled boolean attribute on an input to prevent user interactions and make it appear lighter.,If your application contains a large number of form groups, we recommend building a higher-level component encapsulating a complete field group that renders the label, the control, and any other necessary components. We don't provide this out-of-the-box, because the composition of those field groups is too specific to an individual application to admit a good one-size-fits-all solution.,Provide a function child to manually handle the layout of the FormCheck's inner components.

<Form>
   <Form.Group className="mb-3" controlId="formBasicEmail">
      <Form.Label>Email address</Form.Label>
      <Form.Control type="email" placeholder="Enter email" />
      <Form.Text className="text-muted"> We'll never share your email with anyone else. </Form.Text>
   </Form.Group>
   <Form.Group className="mb-3" controlId="formBasicPassword">
      <Form.Label>Password</Form.Label>
      <Form.Control type="password" placeholder="Password" />
   </Form.Group>
   <Form.Group className="mb-3" controlId="formBasicCheckbox">
      <Form.Check type="checkbox" label="Check me out" />
   </Form.Group> <Button variant="primary" type="submit"> Submit </Button>

How can I set the default value for a FormControl component that has its componentClass set to 'select'? For text FormControls it works fine, but for select it wont work.,Using value instead of defaultValue worked for me.,thank you! you really saved me. this is crazy, the defaultValue doesn't work but value works.,This is still an issue. defaultValue does not show in the select box if children are present. The first option is shown instead.

    const renderOptions = (options) => {
        return options.map((i) => {
            return <option key={i.name} name={i.name} value={i.value}>{i.value}</option>;
        });
    };

    return (
        <FormGroup controlId={field.id}>
            <ControlLabel>{field.label}</ControlLabel>

            <FormControl componentClass="select" defaultValue={field.default} {...field.input}>
                {renderOptions(field.options)}
            </FormControl>

            {field.meta.touched && field.meta.error && <span className="red-text">{field.meta.error}</span>}
        </FormGroup>
    );
};

You've now used a simple select element to get the selected value using ref. Often, however, the select element will be part of the form element.,In that case, the select element’s value can also be fetched using the form element, by using the event handler attached to the select element.,Along with the select element, there is an added property attached called onChange, which is used to get the updated value of the select element.,The select element is a common part of most forms out there to get selected values from the user. In this guide, you have learned how to get the value of the selected item from the select element using ref and the form element. I hope it will help as you play around with the select element.

1import React, { Component } from "react";
2import { Form } from "react-bootstrap";

4class SimpleSelect extends Component {
5  onChangeColor() {
6    console.log(event.target.value);

14        Select any color :

16          as="select"
17          custom
18          onChange={this.onChangeColor.bind(this)}

Toggle contextual overlays for displaying lists of links and more with the Bootstrap dropdown plugin.,Dropdowns are toggleable, contextual overlays for displaying lists of links and more. They’re made interactive with the included Bootstrap dropdown JavaScript plugin. They’re toggled by clicking, not by hovering; this is an intentional design decision.,However, Bootstrap does add built-in support for most standard keyboard menu interactions, such as the ability to move through individual .dropdown-item elements using the cursor keys and close the menu with the ESC key., Examples

<div class="dropdown">
   <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton1" data-bs-toggle="dropdown" aria-expanded="false">
      Dropdown button
   </button>
   <ul class="dropdown-menu" aria-labelledby="dropdownMenuButton1">
      <li><a class="dropdown-item" href="#">Action</a></li>
      <li><a class="dropdown-item" href="#">Another action</a></li>
      <li><a class="dropdown-item" href="#">Something else here</a></li>
   </ul>
</div>
