The DepDrop widget is a Yii 2 wrapper for the dependent-dropdown jQuery plugin by Krajee. This plugin allows multi level dependent dropdown with nested dependencies. The plugin thus enables to convert normal select inputs to a dependent input field, whose options are derived based on value selected in another input/or a group of inputs. It works both with normal select options and select with optgroups as well.
