## How to use moodle forms

Forms are constructed using lib/formslib.php. Using the addElement methods in php a set of different form element types can be added to a form. For more info visit the [Moodledocs](https://moodledev.io/docs/apis/subsystems/form) page for forms

{{< php >}}
    $mform->addElement('button', 'intro', get_string("buttonlabel"));
{{< / php >}}

Form elements are styled using Moodle templates which are rendered through PHP. Themes can override these templates.

Form elements are styled using the .form-control class, see the [Bootstrap](/bootstrap-4.3/forms/input-group/) docs for more info.

## Example form elements

The example form below is showing an iframe with an actual Moodle form. Use the toggle options to display the different states for the form.
