+
+I recently had my first experience using the
+[Entityform module](https://www.drupal.org/project/entityform) in a project. It
+was quite easy to configure with different form types, but then I needed to
+embed the form into an overlay. I was expecting to use the `drupal_get_form()`
+function and render it, but this didn’t work.
+
+Here are the steps that I took to be able to load, render and embed the form.
+
+## Loading the Form
+
+The first thing that I needed to do to render the form was to load an empty
+instance of the entityform using `entityform_empty_load()`. In this example,
+`newsletter` is the name of my form type.
+
+```php
+$form = entityform_empty_load('newsletter');
+```
+
+This returns an instance of a relevant `Entityform` object.
+
+## Rendering the Form
+
+The next step was to be able to render the form. I did this using the
+`entity_form_wrapper()` function.
+
+As this function is within the `entityform.admin.inc` file and not autoloaded by
+Drupal, I needed to include it using `module_load_include()` so that the
+function was available.
+
+```php
+module_load_include('inc', 'entityform', 'entityform.admin');
+
+$output = entityform_form_wrapper($form, 'submit', 'embedded'),
+```
+
+The first argument is the `Entityform` object that was created in the previous
+step (I’ve [submitted a patch](https://www.drupal.org/node/2639584) to type hint
+this within entityform so that it’s clearer what is expected), which is
+required.
+
+The other two arguments are optional. The second argument is the mode (`submit`
+is the default value), and the last is the form context. `page` is the default
+value, for use on the submit page, however I changed this to `embedded`.
+
+I could then pass this result into my theme function to render it successfully
+within the relevant template file.
