Use the field group component to visually group multiple inputs in a form.
This component is intended for styling purposes and does not provide semantic
grouping. For semantic grouping of related form elements, use the <fieldset>
and <legend>
HTML elements instead.
Visual grouping of inputs:
<.field_group>
<.field field={@form[:given_name]} label="Given name" />
<.field field={@form[:family_name]} label="Family name"/>
</.field_group>
Semantic grouping (for reference):
<fieldset>
<legend>Personal Information</legend>
<.field field={@form[:given_name]} label="Given name" />
<.field field={@form[:family_name]} label="Family name"/>
</fieldset>
