|
* Pickable allows to show and hide elements based on the value of a select box. |
|
9
|
|
|
* |
|
10
|
|
|
* Each option is mapped to its associated content by matching the option `value` |
|
11
|
|
|
* with the content `id`. If the option value is numeric, Pickable prefices it |
|
12
|
|
|
* with `choice`. Only the content of the currently selected option is |
|
13
|
|
|
* shown, all other elements associated with the given select box are hidden. |
|
14
|
|
|
* |
|
15
|
|
|
* If no content element of the given `id` is found, Pickable checks for a |
|
16
|
|
|
* `data-request` attribute on the selected option. If a `data-request` URL is set, |
|
17
|
|
|
* Pickable tries to fetch the content remotely and expects an content element with |
|
18
|
|
|
* no additional markup in return. |
