Hello! I would like to share with you a Yii2 widget I designed. This is a input widget which allows users to select a geographical coordinate so that it may be easily processed on the server side.
You may read the README.md in the github repository. It explains the widget usage. Also feel free to ask any questions concerning the widget here.
The JS part is quite raw and is going to be refactored in the future. Nevertheless the widget is already usable and works as expected.
You may see the widget demo here.
