Content structure

Illustration: optionally adds visual context; title: sets the context and works best when short; description: adds more context and works best when short; primary action: sets the main action for the user to complete; secondary action: optionally sets another action to perform, usually cancelling/closing the Dialog.

Behavior

Open on user action

Dialogs are disruptive to the main flow. Only start one after the user has taken an action so it’s clear why it was triggered.

Allow users to close

Users want to feel in control of their actions. Since dialogs interrupt the main user flow, they can invoke negative feelings in users. Make sure users feel in control by offering them a clear option to cancel the dialog and get back to the main flow.

There are situations that all users need to complete before continuing (like accepting terms for an additional service), but it should still be possible to go back to the previous point in the flow.

Do

Give a cancel option.

A dialog with two buttons: agree and cancel.

Don't

Don’t force users to accept only one option.

A dialog with only one option: agree. There is no way to close/cancel the dialog.

Warn about destructive actions

If the action related to the dialog is irreversible or removes something, use a critical button to make the consequences clear to users.

Do

Warn about destructive actions.

A dialog with a warning in the description stating 'You can't do this' and the button is marked as critical (meaning a destructive action).

Don't

Don’t offer destruction choices with no warning about the consequences.

A dialog with no description and actions as normal (even though they're destructive – asking to remove a traveler).

Content

Keep it simple

Dialogs are best as single actions where the context is clear and doesn’t need a lot of explanation. Don’t overwhelm your users with information.

Minimize information

If more information is absolutely necessary, consider adding a text link.

Do

A dialog with a short title and description.

Don't

A dialog with an title covering three lines and a description with three separate paragraphs.

Make action clear from title

The title should make it clear what action users are expected to take or what they’re agreeing to. Keep it short and save any details for the description.

Do

Add a meal?

Don't

Are you sure you want to remove your insurance?
