- not provided
- Scenario
- Designing an interactive PDF form that requires users to select a location and view its associated contact details.
- Observed behavior
- Attempting to create multi-line drop-down entries yields undocumented and unreliable results, as standard PDF drop-down fields do not natively support multi-line formatting.
Ensure you are in form editing mode by opening the 'Prepare Form' tool in your PDF editor before attempting to modify field properties.
Use Separate Text Fields for Additional Details (Recommended Workaround)
Since multi-line drop-down entries are unstable, the best practice is to select the main item from the drop-down and use related text fields to display the extra information automatically.
Instead of forcing a single drop-down field to display three lines of text, separate the data. The drop-down should only act as the selector, while auxiliary text fields present the detailed output.
Add a standard drop-down field to your PDF document. Populate its item list with only the primary identifier, such as the Branch Name, to keep the menu clean and legible.
Below or next to the drop-down menu, insert standard text fields for the extra details like 'Address' and 'Telephone Number'. Set these text fields to 'Read Only' in their properties so users cannot manually overwrite the data.
Use your PDF editor's JavaScript calculation feature on the text fields or configure the drop-down's custom format script to automatically push the corresponding address and phone number to the text fields whenever a specific branch name is selected.

Frequently Asked Questions
Can I force text to wrap in a PDF drop-down list?
No, standard PDF drop-down fields do not support text wrapping. Text will be cut off if it exceeds the width of the field, which is why using auxiliary text fields below the drop-down is the recommended design practice.
How do I make a text field read-only to protect auto-populated data?
Right-click the text field, select 'Properties', navigate to the 'General' tab, and check the 'Read Only' box. This ensures users cannot manually edit the address or phone number after the branch is selected.
Will this text field workaround function correctly on mobile PDF viewers?
Yes, using separate text fields for output is standard PDF form behavior. It is much more likely to be supported reliably by mobile PDF readers compared to unsupported multi-line drop-down scripts.
