# Topics

This option allows your subscribers to choose the topic they are interested in and want to receive push notifications about. 

This can be used in the double opt-in subscription form (the custom one), or with a single opt-in subscription form, by upgrading the bell widget (you must enable both options, [bell widget](/web-push/integration-script/bell-widget.md) and topics)

To enable topics on your project, go to *Settings > Integration Web Push (VAPID) > Topics.*

Type in the names of topics and label keys. Hit the **Save changes** button. From that point, topics will be automatically shown after configuring and publishing a double opt-in subscription form and/or a bell widget.&#x20;

Go to S*ettings > Integration > Subscription form.* Choose the Custom subscription form and fill it in.
