OpenSpecimen allows users to add custom fields using the Custom Forms module. When creating dropdowns with a large set of values(more than 100 values), you need to first create the dropdown using 'Dropdown Manager' and then use it within the form. This page explains the steps to create such dropdowns.
Add dropdown in 'Dropdown Manager'
Create the drop-down in a dropdown manager.
Go to Home→ Extras→ Dropdown Manager.
Click on the 'Add' Button and fill in the values.
Add values to the dropdown
Go to Home→ Extras→ Dropdown Manager→ Import → Dropdown value
Click on Download Template File
Fill the values in the 'Attribute' and 'Value' columns and save the file.
Note
In the 'Attribute' column, fill the 'Unique ID' column value as specified while creating the new dropdown above.
In the 'Value' field, fill the dropdown values.
To make sure the values have been uploaded, go to Import → View Past Imports and check the import was successful.
Add Field to Form
Once the values are added in the dropdown manager, you can then fetch these values by adding a 'Permissible Value' control.
Navigate to the “Forms“ module.
Click on the “+Create“ button.
Add “Permissible Value“ control field → Add Details like the label, attribute, and so on.
