Example #

<sp-field-label for="horizontal">
    Choose from horizonally placed options
</sp-field-label>
<sp-field-group horizontal id="horizontal">
    <sp-checkbox>Checkbox 1</sp-checkbox>
    <sp-checkbox>Checkbox 2</sp-checkbox>
    <sp-checkbox checked>Checkbox 3</sp-checkbox>
    <sp-checkbox>Checkbox 4</sp-checkbox>
    <sp-checkbox>Checkbox 5</sp-checkbox>
</sp-field-group>

Vertical #

<sp-field-label for="vertical">
    Choose from vertically placed options
</sp-field-label>
<sp-field-group vertical id="vertical">
    <sp-checkbox>Checkbox 1</sp-checkbox>
    <sp-checkbox>Checkbox 2</sp-checkbox>
    <sp-checkbox>Checkbox 3</sp-checkbox>
    <sp-checkbox>Checkbox 4</sp-checkbox>
    <sp-checkbox checked>Checkbox 5</sp-checkbox>
</sp-field-group>

Help text #

Help text can be accessibly associated with an <sp-field-group> element by using the help-text or negative-help-text slots. When using the negative-help-text slot, <sp-field-group> will self manage the presence of this content based on the value of the invalid property on your <sp-field-group> element. Content within the help-text slot will be show by default. When your <sp-field-group> should receive help text based on state outside of the complexity of invalid or not, manage the content addressed to the help-text from above to ensure that it displays the right messaging and possesses the right variant.
