+The `lazy_load` option enables deferred loading of tab content, improving performance by fetching data only when the tab is clicked. By default, `lazy_load` is set to `false`, ensuring that all tabs load immediately. However, in form views, this option is automatically disabled to prevent data loss during form submission.
