In a text field, how can I auto populate user's choices with a list of previously created issues?

[kdickason]

We have a custom field of the type Text fields (Single Line). When user hits down arrow from field, the field populates with a list of issues of a certain type, from which the user can select. How is this set up? Do you have to buy an add-on to do this? We do use Jira Automation for Server--but do not see a way to set this up.

Hi @kdickason can you share some screenshot? I'm not sure what you mean by "hits down arrow". If it is really simple text field, the values you see can be probably only form values stored in your browser.

I'm looking for functionality that provides a dynamic populated selection list in a drop down for a single select custom field.  I want to dynamically populate the options using issues of a certain issue type from another project (so a user can select the issue from the other project in the select list).   My reading has shown me that a third party tool such as ScriptRunner is needed.

Yeah, you will definitelly need something. Or you can implement your own app, but it's quite advanced. Script runner provides field of Issue picker type.
