Some sections in the page builder have a Pro badge. Can I still use them?

Yes. The Pro badge only marks which tier of designs a look belongs to. It doesn't lock the section. Click the tile and it is added to your page like any other section, with no extra step or charge in the builder.

Fill in its content and click Save. Check it on desktop and mobile with the Desktop / Tablet / Mobile switch, since some richer designs work best with good-quality images.

What does depend on your plan is whether you can use the Normal Builder at all. If a page shows an Upgrade tag next to Normal Builder, that is the plan limit.
