Alpaca provides the easiest way to generate interactive HTML5 forms for web and mobile applications. It uses JSON Schema and simple Handlebars templates to generate great looking, dynamic user interfaces on top of Twitter Bootstrap, jQuery UI, jQuery Mobile and HTML5.
Each time the dropdownselection of the optiontree is changed all dropdown boxes are shifted to the right.
I tried it in my own form as well as in example 1 on: http://alpacajs.org/docs/fields/optiontree.html
Here is what the form looks like after the first selection:![image](https://user-images.githubusercontent.com/39065432/45891549-26630d00-bdc6-11e8-9702-00cd8ab58710.png)
And this is the result after switching between 'Basketball' and 'Baseball' about 10 times:![image](https://user-images.githubusercontent.com/39065432/45891611-50b4ca80-bdc6-11e8-95c0-2c83f220f0cf.png)
