    <p>I've recently been using Angularjs in my project. I'm trying to create a dynamic form which enables users to create crossword puzzle questions. I was thinking of using angularjs to allow users to add additional rows and columns into their answers. In my form, I've created an input called "answer" which has 2 child element row and column, and "column" has it's own child element as well. This is what I have done so far:</p> <p>html page:</p> <pre><code>Answer for the question: [&lt;a href='' ng:click='form.answer.$add()'&gt;AddRow&lt;/a&gt;] &lt;table&gt; &lt;div ng:repeat='ans in form.answer'&gt; &lt;tr&gt; &lt;td&gt;{{ans.row}}&lt;/td&gt; &lt;div ng:repeat='col in ans.column'&gt; &lt;td&gt;&lt;input type='text' name="col.word" ng:required/&gt;&lt;/td&gt; &lt;/div&gt; [&lt;a href='' ng:click='col.$add()'&gt;AddCol&lt;/a&gt;] &lt;/tr&gt; &lt;/div&gt; &lt;/table&gt; </code></pre> <p>javascript:</p> <pre><code>questionCtrl.$inject = ['$invalidWidgets']; function questionCtrl($invalidWidgets) { this.$invalidWidgets = $invalidWidgets; this.master = { title: 'title', descr:'description here', answer: [{row:'1', column:[{word:'z'},{word:'x'}]} ,{row:'2', column:[{word:'a'},{word:'w'}]} ], user:'' }; this.cancel(); } questionCtrl.prototype = { cancel : function(){ this.form = angular.copy(this.master); }, save: function(){ this.master = this.form; this.cancel(); } }; </code></pre> <p>I've manage to allow users to add rows to their answers, but I can't display the column array's element's at all. Is this because there is sonething wrong with my codes or Angularjs does not allow double arrays in their forms? Sorry if my explanation isn't clear.</p>

    1. COThe html is invalid - you can't have <div> inside <tr>, but outside <td>, I guess browser strips this out. Btw, can you update to the latest Angular ? Looks like you're using very old one...

    2. COThanks! It worked :) . Using span instead. Anyway, i'm not certain what version i'm using actually. Was kinda following an example that I saw in a website.

    3. COYou can't have spans inside `<tr>` or `<table>` (only inside `<td>`), Chrome might allow it, but not IE. Just posted a reply with working code. You can grab the latest Angular at http://code.angularjs.org/1.0.0rc1/ (you're using 0.9.*)

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).
