    1. COHi @Sparky , I have added my codes inside a jsfiddle http://jsfiddle.net/dHrvT/15/ . However, is it ok for you to add your solution and let me know if it works. I tried in real staging links and was unable. I do believe your solution works.. I just can't seem to integrate one with the other

    2. CO@Himu, [I fully answered your question as you originally posted it](http://jsfiddle.net/JVWu2/). There was nothing mentioned in your OP about integrating this with `prettyCheckable`. IMO, this is a whole different issue. The jQuery Validate plugin is only looking at your real checkbox elements and until you can figure out how to toggle those, this is never going to work.

    3. CO@Himu, I also notice that your jQuery code is unnecessarily repetitive. Nearly all of your `.on('change')` handlers could be combined into one and you should only need to call `.prettyCheckable()` one time. It's just a matter of using the proper jQuery selectors to select all target elements at once.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
