+### Turbo submits with
+There is a turbo attribute [(data-turbo-submits-with)](https://turbo.hotwired.dev/reference/attributes) that replaces the content of a submit button while the request is processing. This only works on `f.button` or `f.primary` not on `f.submit` and forces `render_as_button: true` on `f.primary` since `<submit>` tags only allow text content.
+
+You can have `bootstrap_form` put up a default bootstrap spinner while the request is processing with the following:
+```erb
+<%= f.button "Save", data: { turbo_submits_with: f.spinner } %>
+
+<%= f.button "Save", data: { turbo_submits_with: "<span>Loading...</span>" } %>
+```
+
+```html
+<button class="btn btn-secondary" data-turbo-submits-with="<span>Loading...</span>" name="button" type="submit">Save</button>
+```
