Bootstrap - Checkbox and Radios

This chapter will discuss about checkbox and radios utilities provided by Bootstrap. Checkboxes allow you to select one or more alternatives from a list, whereas radio buttons allow you to choose only one.

Approach

  • Bootstrap provides wrapper class .form-check for improved layout and behavior of browser default checkboxes and radios elements. It also allows greater customization and cross browser consistency.

  • .form-check-label class is used to show checkbox labels.

  • .form-check-input class is used for input type checkbox.

  • Structurally, the input and label act as siblings.

Bootstrap's custom icons are used to display checked or indeterminate states.

Checkbox

Checkboxes select one or several options from a list.

Without Labels

  • Skip the wrapping class .form-check for checkboxes and radio that have no label text.

  • Provide an accessible name for assistive technologies (for instance, using aria-label). For information, refer accessibility section of the Forms overview section.

Toggle Buttons

  • Use .btn class on the <label> element rather than .form-check-label to create button-like checkboxes and radio buttons. These toggle buttons may also be placed together in a button group.

  • Use .btn-check class which indicate that the input is of a button-type checkbox.
