Yii2 What is the analogue with dependencies dropDownList kartik\select2\Select2?

Question

Yii

We need a similar widget, but with the exception of the following problems:
1. For 'multiple' => true to work ( use kartik\depdrop\DepDrop - does not work)
2. It is necessary that it works similar to ajax

Answer 1

To do this, you do not need to look for anything, you can implement it yourself using regular yii2 tools, just like it was done in kartik\select2\Select2.
Read the documentation, it's not as difficult as it might seem.
