How would I render a dynamic definition list using AngularJS?

Question

How would I render a dynamic definition list using AngularJS?

Example:

Data:

[
    {
        key: 'a',
        value: 'x'
    }, {
        key: 'b',
        value: 'y'
    }
]

Desired HTML:

<dl>
    <dt>a</dt>
    <dd>x</dd>
    <dt>b</dt>
    <dd>y</dd>
</dl>

The example at http://docs.angularjs.org/tutorial/step_08:

<dl>
    <dt>Availability</dt>
    <dd ng-repeat="availability in phone.availability">{{availability}}</dd>
</dl>

works for a dynamic number of dds and a static number of dts, but not a dynamic number of both.

Answer 1

A new feature which allows ng-repeat-start/ng-repeat-end was added in Angular 1.2.

With this feature, you can write your html like this:

<dl>
  <dt ng-repeat-start="i in items">{{i.key}}</dt>
  <dd ng-repeat-end>{{i.value}}</dd>
</dl>

See this plnkr for a full working example.

Answer 2

I've created a directive called repeatInside to solve problems like this one.

<dl repeat-inside="word in dictionary">
    <dt>{{word.name}}</dt>
    <dd>{{word.definition}}</dd>
</dl>

Answer 3

This is a problem, because you need to wrap it with some element in order to do repeating. And that's not gonna be a valid html - you would get into the same trouble with unordered lists or tables...

<dl>
  <div ng-repeat="i in items">
    <dt>{{i.key}}</dt>
    <dd>{{i.value}}</dd>
  </div>
</dl>

I guess the div inside dl is not allowed by spec, but it works - at least in Chrome :-D

We plan to support ng-repeat inside a comment to support this.

Answer 4

This answer didn't seem to work for me in Angular v1.2.7 so I wanted to post a slight variation that worked well for me:

<dl>
    <dt ng-repeat-start="(key, value) in items">{{key}}</dt>
    <dd ng-repeat-end>{{value}}</dd>
</dl>
