Why can't I draw a click area across certain areas?

If you've tried clicking and dragging across a screen in heatmap results and noticed your selection disappears or stops at a certain point, you're not doing anything wrong. This is expected behavior; here's what's causing it and how to work with it.

What's happening?

Click areas are scoped to a single frame. In prototypes, a frame is the container that holds each section of your screen. Prototypes with scrollable content and fixed elements (like a bottom navigation bar or a sticky header) use separate frames for each of those sections, and each frame renders independently.
When you drag a click area across a frame boundary, Maze can't create a single selection that spans both. The area either stops drawing or disappears because your selection crossed into a different frame.

How to work with it

You can still analyze clicks across the full screen; you just need separate click areas for each section.

For example, if your prototype has a scrollable content area and a fixed navigation bar, draw one click area within the scrollable section and another within the nav bar. Each area will show its own click metrics independently.

You can add as many click areas as needed on a single screen, so you can still build a full picture of click activity.

Which prototypes are affected?

This applies to any prototype that uses elements such as:

• Scrollable frames: content that extends beyond the visible screen and scrolls vertically or horizontally

• Fixed elements: layers that stay in place while other content scrolls, like nav bars or headers

• Sticky elements: layers that scroll at first, then lock to the top of their container

If your selection stops unexpectedly, it's usually hitting one of these frame boundaries.
