Text Input Search from Hosted List

Description:

The Text Input Search from Hosted List extension enables a search-ahead (autocomplete) experience on text input fields using values pulled from a hosted CSV list (e.g., Google Sheets). Users can either pick from suggested entries or, optionally, enter custom values.

Setup Instructions

1. Required Metadata for Search-Ahead

On any text input field, add the following metadata:

• Key: search_list_url

• Value: Public CSV/Google Sheets URL to load options from

Optional Attribute:

• search_ahead_min_chars: Minimum characters to trigger dropdown (default is 3)

By default, the extension validates that submitted values match a record from the list. To turn off the validation on the same text input, add this field-level metadata:

• Key: skip_auto_match_validation

• Value: true

This will bypass the strict match requirement during form validation.

Notes

• The extension automatically detects whether your CSV source is a Google Sheet and fetches it using export formatting.

• Style definitions for the autocomplete dropdown are inserted into the body tag automatically.

• Ensure your CSV contains a single column of valid options.

• You can apply this to multiple fields by assigning search_list_url metadata to each.
