Hello,I want to show a topoplot (EEG scalp map) in LimeSurvey where participants can click on electrodes, and each click should select a multiple-choice option (e.g. Fz, Cz, P3). The selection should be saved as normal survey answers (not just X/Y coordinates).My goal:

• Image of topoplot as background
• Clickable points (hotspots) at electrode locations
• Clicking toggles the corresponding multiple-choice option
• Participant can select multiple electrodes

Question: Is there a known solution or example in LimeSurvey?LimeSurvey version: Version 6.8.2+241203
