How to use multiple select in yii2 searchModel?

Question

Yii

There is a product filter in the backend application, everything works fine, but the filter does not accept multiple select (For example, if I want to view products from several categories). As a result, everything is filtered by the last selected option. Are there any standard means of implementing this issue or how do you solve such a problem?

Answer 1

See why you are sending 1 value, and not several.
Give code to searchModel and gridView. Otherwise it's guesswork.
