    <p>I'm trying to make a basic calendar to help automate Timesheets at work using Angular.js and Chrome Extensions, but for now I am stuck on this part. </p> <p>Below you can see two arrays: <code>pastTwoWeeks</code> which is a list of dates from today back 14 days and Timesheet <code>entries</code> which were retrieved from an API - these will actually be objects with many properties but for now I am just using a simple date.</p> <p>Here's a jsfiddle, am I on the right track? Thanks <a href="http://jsfiddle.net/v599n/" rel="nofollow">http://jsfiddle.net/v599n/</a></p> <pre><code>var pastTwoWeeks = ['15/10/2013', '14/10/2013', '13/10/2013', '12/10/2013', '11/10/2013', '10/10/2013', '09/10/2013', '08/10/2013', '07/10/2013', '06/10/2013', '05/10/2013', '04/10/2013', '03/10/2013', '02/10/2013']; var entries = ['11/10/2013', '11/10/2013', '11/10/2013', '11/10/2013', '10/10/2013', '10/10/2013', '10/10/2013', '09/10/2013', '09/10/2013', '09/10/2013', '08/10/2013', '08/10/2013', '07/10/2013', '07/10/2013', '04/10/2013', '04/10/2013', '03/10/2013', '03/10/2013', '02/10/2013', '02/10/2013', '02/10/2013', '02/10/2013', '01/10/2013', '01/10/2013', '01/10/2013']; var calander = {}; for(var j=0; j&lt; pastTwoWeeks.length; j++) { var key = pastTwoWeeks[j]; if (key in calander == false) { calander[key] = {}; } for(var i = 0; i&lt; entries.length; i++) { var entry = entries[i]; if(entry === key){ calander[key][entry]; console.log(key + " " + entry); } } } </code></pre> <p>What I want to achieve:</p> <ul> <li>15/10/2013 </li> <li>14/10/2013 </li> <li>13/10/2013 </li> <li>12/10/2013 </li> <li>11/10/2013 (4 entries) <ul> <li>11/10/2013</li> <li>11/10/2013</li> <li>11/10/2013</li> <li>11/10/2013</li> </ul></li> </ul> <p>etc...</p>

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.
