Form fields (React Select and Date Picker) are cut or missing in screenshots generated by html2canvas in a React Hook Form setup

[mansoorsaleem444]

Summary

When using html2canvas to capture a screenshot of a form built with React Hook Form, some input fields — especially custom components like react-select dropdowns and date pickers — are partially rendered or completely cut off in the output image.

This issue seems to affect third-party components that render dropdowns or floating elements via portals or overlays.

Steps to Reproduce

1. Create a React form using react-hook-form
2. Add inputs using:
   • react-select for dropdowns
   • A date field using react-datepicker or Material UI DatePicker
3. Wrap the form in a ref and pass it to html2canvas
4. Click a button to trigger a screenshot
5. Observe that:
   • Some form controls are missing entirely
   • Dropdowns or calendars are cut off or not rendered correctly

---

Expected Behavior

All visible fields and custom inputs (including dropdowns and date pickers) should appear correctly in the canvas/screenshot.

---

Actual Behavior

• Some custom components (like react-select) are missing or rendered incorrectly
• Date picker popups or dropdowns are either invisible or cut off
• Possibly related to components being rendered in portals or absolute positioning[
