Overview
#

The checkbox is generally used to select one of two possible values in a form.

Layout
#

  • Aligned with container margin
  • When used in a group, vertically stacked
  • Hierarchical nesting is avoided

Guidelines
#

  • Labels should be short and concise
  • Checkbox should not be used to make real-time changes; for this situation, use a KSwitch component instead

States
#

The checked state represents an affirmative value.

Checkboxes can also have a "partially-checked" or "indeterminate" state used in cases where the value is neither true nor false, such as when a subset of a topic is selected:

A user cannot enter the indeterminate state by interacting directly with the checkbox; it only occurs due to external interactions.

Example: Label content
#

Label content can be passed via the label property: 

      <KCheckbox label="First lesson" />
In more complex situations, for example when another component is responsible for rendering the label, the default slot can be used: 

      <KCheckbox>
        <KLabeledIcon
          icon="lesson"
          label="First lesson"
        />
      </KCheckbox>
✘ Don't

Don't wrap the default slot's content in <label>:


          <KCheckbox>
            <label>
              <KLabeledIcon
                icon="lesson"
                label="First lesson"
              ></KLabeledIcon>
            </label>
          </KCheckbox>

That would cause two nested <label> elements to be rendered as KCheckbox takes care of it already.
