Checkbox

React Bootstrap 5 Checkbox component

The checkbox is a component used to allow a user to make multiple choices that are broadly used in forms and surveys. Checkboxes are used to select one or several options in a list, while radio (option) buttons are for selecting one option from many.


Basic example

Browser default checkboxes and radios are replaced with the help of .form-check, a series of classes for both input types that improves the layout and behavior of their HTML elements, that provide greater customization and cross browser consistency. Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.

Structurally, our <input>s and <label>s are sibling elements as opposed to an <input> within a <label>. This is slightly more verbose as you must specify id and for attributes to relate the <input> and <label>.

We use the sibling selector (~) for all our <input> states, like :checked or :disabled. When combined with the .form-check-label class, we can easily style the text for each item based on the <input>'s state.

        
            
            import React from 'react';
            import { MDBCheckbox } from 'mdb-react-ui-kit';
    
            export default function App() {
              return (
                <>
                  <MDBCheckbox name='flexCheck' value='' id='flexCheckDefault' label='Default checkbox' />
                  <MDBCheckbox name='flexCheck' value='' id='flexCheckChecked' label='Checked checkbox' defaultChecked />
                </>
              );
            }
          
        
    

Disabled

Add the disabled property and the associated <label>s are automatically styled to match with a lighter color to help indicate the input’s state.

        
            
            import React from 'react';
            import { MDBCheckbox } from 'mdb-react-ui-kit';
    
            export default function App() {
              return (
                <>
                  <MDBCheckbox name='disabledCheck' value='' id='flexCheckDisabled' disabled label='Disabled checkbox' />
                  <MDBCheckbox name='disabledCheck' value='' id='flexCheckCheckedDisabled' defaultChecked disabled label='Disabled checked checkbox' />
                </>
              );
            }
          
        
    

Inline

Group checkboxes or radios on the same horizontal row by adding inline property.

        
            
            import React from 'react';
            import { MDBCheckbox } from 'mdb-react-ui-kit';
    
            export default function App() {
              return (
                <>
                  <MDBCheckbox name='inlineCheck' id='inlineCheckbox1' value='option1' label='1' inline />
                  <MDBCheckbox name='inlineCheck' id='inlineCheckbox2' value='option2' label='2' inline />
                  <MDBCheckbox name='inlineCheck' id='inlineCheckbox3' value='option3' label='3 (disabled)' disabled inline />
                </>
              );
            }
          
        
    

Without labels

Omit the label property for checkboxes and radios that have no label text. Remember to still provide some form of label for assistive technologies (for instance, using aria-label).

        
            
            import React from 'react';
            import { MDBCheckbox } from 'mdb-react-ui-kit';
    
            export default function App() {
              return (
                <>
                  <MDBCheckbox name='checkNoLabel' id='checkboxNoLabel' value='' aria-label='...' />
                  <MDBCheckbox name='checkNoLabel' id='checkboxNoLabe2' value='' aria-label='...' />
                </>
              );
            }
          
        
    

Toggle buttons

MDB’s .btn styles can be applied to <label>s, to provide checkbox style button toggling. Add an MDBCheckbox with a btn property to toggle the input state. You can change the color using btnColor property.

        
            
            import React from 'react';
            import { MDBCheckbox, MDBBtnGroup } from 'mdb-react-ui-kit';
    
            export default function App() {
              return (
                <MDBBtnGroup>
                  <MDBCheckbox name='btnCheck' btn id='btn-check' wrapperTag='span' label='Checkbox button' />
                  <MDBCheckbox name='btnCheck' btn id='btn-check2' wrapperClass='mx-2' wrapperTag='span' label='Checkbox button' defaultChecked />
                  <MDBCheckbox name='btnCheck' btn id='btn-check3' wrapperTag='span' label='Checkbox button' />
                </MDBBtnGroup>
              );
            }
