I was able to replicate the issue when I opened this form. There's a delay when you click the drop down and the form collapse. Here's a screen capture:
The solution here is to disable the "Continue Forms Later" option in the Preferences wizard. Here's how:
1. In the Form Builder, click the "Preferences" button.
2. Go to "Advanced" tab and disable the "Continue Forms Later" option.
Here's the result after disabling the Continue Forms Later option.
The Continue Forms Later is the "Autofill" function of the form. The data that was entered previously are being stored in the user's browser local storage. This is the reason why it is slow. Here's a guide: https://www.jotform.com/help/227-How-to-Enable-Auto-Fill-on-Forms.
This function is not recommended for long forms. If you want to use a feature where your users can save the form and resume later, please refer to this guide: https://www.jotform.com/help/97-How-to-Save-Forms-and-Continue-Later.
Hope that helps. Thank you.
