In views filter I have added user reference field and its showing me as select drop-down.I have exposed that field in the filter.

Those user reference fields are related to a content type, but I want those as auto-complete fields instead of drop-down, just as taxonomy fields can be drop-down or auto-complete fields.

The issue with select list is that there are thousands of users in that list and it is taking time to load all values and render the page.

How can I achieve this?
