    1. CO@Peter, yes you might be right. This article explains more and has a workaround for incompatible browsers: https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/indexOf

    2. COYou can ease up usage of this by adding a `delete` function on the array prototype. I’ve taken use of your example in **[a gist](https://gist.github.com/zykadelic/5069236#file-array-delete-js)** that deletes all targeted elements in the array instead of just 1.

    3. COIt’s too late to edit my last comment but I just want to correct myself. Calling `delete` on an array is no go in IE 8. I’ve updated the gist to use `destroy` instead.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
