Multiple options for search attribute

you can try to use tag search attribute then separated by comma – https://wp-events-plugin.com/documentation/event-search-attributes/

Yup- have certainly looked at that. The idea behind using the search string option is finding events that have been submitted by readers- that might not be tagged correctly, or tagged at all.

What you’re looking for is a kind of autocomplete which isn’t something that’s available out-of-the-box. It might be something that can be done with custom coding.

bummer…

this is not yet available at the moment however maybe you can try and modify this user shared snippet – https://gist.github.com/xymox12/4718315
