Configuring a Conveyor Belt
Set up a Conveyor Belt's scrolling options, belt motion, and scoring in a roomy Configure dialog, opened right from the canvas.
A Conveyor Belt scrolls a row of options past the learner, who taps the ones that fit the rule (for example, "Tap every verb"). It has a large setup — the options themselves, how the belt moves, and how it's graded — so all of it lives in a dedicated Configure dialog with room to work, instead of being squeezed into the narrow right sidebar.
Opening the Configure dialog
Select a Conveyor Belt on the canvas. A floating ⚙ Configure button appears just above it.
Click ⚙ Configure to open the dialog. Alongside the settings you'll see a live preview of the belt, so you can see what it will look like on the canvas while you edit (you can't see the belt itself behind the dialog). From top to bottom the dialog has:
- Scoring — whether the belt contributes to the score, and how it's graded. The Scoring switch, Points, and Group work the same for every scorable widget (Points is hidden when Scoring Mode is Per option, which doesn't use it).
- Content — how the belt renders and moves, plus the list of options and which ones are correct.
Setting up the options
Work in the Content section:
- Mode — render the options as Text labels or as Images. Image options show a thumbnail and let you pick a picture from your asset library.
- Options — add up to 50 options. Reorder them with the up/down arrows, edit each one's text (or image), and remove any you don't need.
Each option you add scrolls past on the belt. Start with fewer options at a slower speed and add more once you've confirmed learners can keep up.
Setting how the belt moves
Still in Content:
- Direction — scroll Horizontal (left/right) or Vertical (up/down).
- Scroll From — the edge new options enter from (Left/Right for a horizontal belt, Top/Bottom for a vertical one).
- Speed (px/s) — how fast the belt scrolls, in pixels per second.
- Feedback — show correct/incorrect feedback right away when an option is tapped (Immediate), or hold it until the belt ends (Deferred). Either way, every picked option is outlined with its result once the belt ends.
- Feedback Duration (ms) — how long an Immediate flash stays on screen before it fades.
Grading the belt
Scoring is on by default, so the dialog opens with the shared on/off, points, and group controls already at the top, plus the belt's own grading options:
- Correctness Mode — whether the learner must tap All correct options, At least one, or At most one. It also decides when the belt ends: once every correct option is picked, on the first correct pick, or on the first pick. A wrong pick along the way doesn't stop the belt ending — it just marks the answer wrong. See Correctness modes.
- Scoring Mode — award a single Whole score for getting the belt right, or accumulate points Per option for each correct tap.
- Points per option — appears when Scoring Mode is Per option: the points each correct tap is worth. Below it, the dialog shows what the whole belt is worth (points per option × the number of correct options with All correct; just one option's points with At least one or At most one, which end on a single pick). Wrong taps don't take points away in this mode.
Once scoring is on, each option in Content gets a Correct toggle — mark the options that count as correct answers, right next to the option text.
Saving your changes
Nothing you change in the dialog affects the widget until you save it. The canvas keeps showing the last saved version while you work.
- Save applies your Content and Scoring changes to the widget.
- Cancel throws the changes away and leaves the widget as it was. Pressing Esc, clicking the ✕, or clicking outside the dialog does the same thing. If you've made changes, you'll be asked to confirm before they're discarded, so an accidental click can't lose your work.
Heads-up warnings
The dialog watches for a couple of common setup mistakes and shows an inline warning next to the control it affects (and a one-line summary near Save):
- Fewer than two options.
- An option is blank (no text and no image).
- Scoring is on, but no option is marked correct.
These are reminders, not roadblocks — you can still Save with a warning showing if that's really what you want.
What stays in the sidebar
Only Content and Scoring move into the Configure dialog. Style & Layout — the belt and cell colors, the background image, cell shape and gap, fonts, the auto-fit font size range, the feedback border colors and width, and the cursor — still lives in the right sidebar, the same as every other widget. So do the widget's behaviors/triggers, visibility, and position. Select the widget and the sidebar shows its Style & Layout settings while the dialog handles the options and grading.
