The {@link #title} + * config will be rendered as the fieldset's `legend`. + * + * While FieldSets commonly contain simple groups of fields, they are general {@link Ext.container.Container Containers} + * and may therefore contain any type of components in their {@link #items}, including other nested containers. + * The default {@link #layout} for the FieldSet's items is `'anchor'`, but it can be configured to use any other + * layout type. + * + * FieldSets may also be collapsed if configured to do so; this can be done in two ways: + * + * 1. Set the {@link #collapsible} config to true; this will result in a collapse button being rendered next to + * the {@link #title legend title}, or: + * 2. Set the {@link #checkboxToggle} config to true; this is similar to using {@link #collapsible} but renders + * a {@link Ext.form.field.Checkbox checkbox} in place of the toggle button. The fieldset will be expanded when the + * checkbox is checked and collapsed when it is unchecked.
