I need to create a drop down list with countries, there is a way to customize and fill a dropdown list from an external database?

Thanks for the help

Regards.

Hello,

Not included in LimeSurvey directly, but you have some workarounds:
docs.limesurvey.org/tiki-index.php?page=...wers_for_text_inputs

You can use your own database with a little adaptation (see jqueryui.com/autocomplete/ option)
