Suggestions in a dropdown field with custom user input enabled

[studententyp]

Hello community,

I'm creating a form which concludes an dropdown field with multiple choices and custom user input enabled. How can I add autofill/autocomplete suggestions from the entry list based on the user input?

Example:

Entrylist: Test, Tree, House

User Input: Tr

Suggestion: Tree

Thank you in advance for your help,

regards,

Tobias

I don't think that's possible. You can maybe filter the list of items based on the user's input, but it will be tricky to implement.
If you want to be able to "filter" the list I would recommend doing it using a separate text tool, like in this (paid-for) tool I've created that does just that: http://try67.blogspot.com/2012/11/acrobat-create-live-filtered-list.html

Thank you for your response. 

I quickly looked through the JS Api and didnt find a way to open the ComboBox-list by JavaScript (to show the filtered items list) - do you know a way for archiving that?

That's not possible with a script. The user will have to do it manually.
