Increase autocomplete dropdown limit for existing contacts? (webform)

Question

I have a couple of CiviCRM integrated webforms with 'existing contact' enabled, using the autocomplete option. My problem is that the fields only return the first 12 matching records, even when there are more matches.

For example our DB has 27 records with 'University' in their names. If a user enters 'University' the dropdown lists the first 12 records (Botswana University; Cambridge University etc). To return 'University of Zululand' users need to enter 'University of Z', but this isn't obvious to the user

Is it possible to increase the number of existing contact results returned, and if so where?

Alternately has anyone found a different way around the problem e.g. would it be possible to add a "click for more results" at the bottom of the dropdown list?

(We are using Drupal 7.82; Webform 7.x-4.24; Webform CiviCRM Integration 7.x-5.6)

Answer 1

The limit of 12 is hard-coded in the webform_civicrm module. You can find the line here

https://github.com/colemanw/webform_civicrm/blob/8276d951fc1ab00e3b6b989fb3f2b594d41ba3a9/includes/contact_component.inc#L669

The most crude way to change it is to edit the source code. You will lose this change the next time the webform_civicrm module on the site is updated.

If you are a developer, you can make the limit configurable and submit a PR to the Drupal project.

Or add some instructions for your user, explaining the first twelve results are shown, so it is better to be specific.
