Bootstrap3 Dialog give another level to create Bootstrap modal become flexible. It's write on javascript, and I don't know much about it. So I made some wrapper to call this modal with Yii2 framework. IMHO, rather than create .php file and create javascript on it, you can do a lot of trick with Yii2 feature to create Bootstrap's Modal more efficient.

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist "mdscomp/yii2-bootstrap-dialog" "~1.0"

or add

"mdscomp/yii2-bootstrap-dialog": "~1.0"

to the require section of your composer.json file.
