Usage

The Modal component consists of an overlay, a dialog and an optional close button. You can use any element to toggle a modal dialog. To enable the necessary JavaScript, add the data-uk-toggle attribute. An <a> element needs to be linked to the modal’s id. If you are using another element, like a button, just add the data-uk-toggle="target: #ID" attribute to target the id of the modal container.

Add the data-uk-modal attribute to a <div> element to create the modal container and an overlay that blanks out the page. It is important to add an id to indicate the element for toggling. Use the following classes to define the modal’s sections.

ClassDescription
.uk-modal-dialogAdd this class to a child <div> element to create the dialog
.uk-modal-bodyAdd this class to create padding between the modal and its content.
.uk-modal-titleAdd this class to a heading element to create the modal title.
.uk-modal-closeAdd this class to an <a> or <button> element to create a close button and enable its functionality.

Media

If you want to display media, you should first check, if the Lightbox component doesn’t already offer everything you need. However, you can also use the modal to have more control over the markup to wrap your media in.

Note Use the data-uk-video attribute from the Video component to make sure videos are stopped when the modal is closed.

Groups

You can group multiple modals by linking from one to the other and back. Use this to create multistep wizards inside your modals.

Methods

The following methods are available for the component:

Show

Shows the Modal.

Hide

Hides the Modal.

Note While the modal dialogs work perfectly, customizing padding requires a custom-compiled UIkit JavaScript. If you’re unfamiliar with compiling your JavaScript, it’s advisable to build the modal using HTML.

The component comes with a number of prepared modal dialogs that you can use for user interaction. You can call the dialog directly from JavaScript and use callback functions to process the user input.

CodeDescription
UIkit.modal.alert('UIkit alert!')Show an alert box with one button.
UIkit.modal.confirm('UIkit confirm!')Show a confirm dialog with your message and two buttons.
UIkit.modal.prompt('Name:', 'Your name')Show a dialog asking for a text input.
UIkit.modal.dialog('<p>UIkit dialog!</p>');Show dialog with any HTML content.

To process the user input, the modal uses a promise based interface which provides a then() function to register your callback functions. The UIkit.modal.dialog function however will return the modal itself.

The returned promise has a property dialog, which holds a reference to the modal itself. This lets you manipulate e.g. the markup of the modal’s element.

To translate the button labels, the dialog functions accepts an optional options object parameter. This has a key i18n and two properties ok and cancel.

Accessibility

The Modal component adheres to the Dialog (Modal) WAI-ARIA design pattern and automatically sets the appropriate WAI-ARIA roles and properties.

  • The modal has the dialog role and the aria-modal property.

The Close component automatically sets the appropriate WAI-ARIA roles and properties.

  • The close icon has the aria-label property, and if an <a> element is used, the button role.

Keyboard interaction

The Modal component can be accessed through keyboard using the following keys.

  • The esc key closes the modal. This behaviour is disabled if the bg-close: false option is set.
