@YenMejia_Voce Do you refer to the static list and how many suggestions you can maintain? 

You should reach out to Qualtrics support for the correct answer.

In a past project, we had to load from a very long list, and I think after ~2000 entries, we started facing some performance degradation and that’s why moved to a custom autocomplete solution.

Hi @YenMejia_Voce ,

Regarding the Static list option, the support page does not provide specific information about the number limits.

However, if you are referring to the Supplemental Data Source, the support page states the following:

• The maximum number of rows is 100,000.
• The maximum number of columns is 30.
• For searchable fields, each cell can have a maximum of 200 bytes.
• For non-searchable fields, each cell can have up to 5000 bytes/characters.
• Files should not exceed 10MB in size.
• The file format should be either TSV or UTF-8 encoded CSV.
