Yes, you can.
Any CTA button in LandingRabbit can open a pop-up/modal window instead of navigating to another page.
Select the CTA button you want to edit.
In the editing panel, click the Embed tab.

Add the content you want to display in the modal. This could be a HubSpot form, a Calendly calendar, YouTube video, or any other embed code.
Tick the checkbox to Open in a modal.
When a page visitor clicks your button, the pop-up opens in the center of the screen.

The embedded content, whether it's a form, calendar, video, or anything else, displays inside the modal.
Visitors can close the modal by clicking anywhere on the background or the X button in the top right corner.
Modals are useful when you want to capture leads or show additional content without sending visitors to a different page.
