Description

Turns a text input into a list widget with autocompletion. This plugin adds a new formfield type textboxlist to DataForms.

Usage

An html input field can be turned into a textboxlist widget either using javascript or using the jqTextboxList css class.

Using javascript:

<input type="text" name="tags" />

<script>
jQuery(function($) {
  $("input[name='tags']").textboxlist(options);
});
</script>

Using css:

<input type="text" name="tags" class="jqTextboxList {options}" />

In both cases options is a json object to customized the textboxlist to your needs.

Events

Instead of specifying callbacks using the onSelect or onDeselect options, custom events are emitted by the textboxlist widget that your own code can be bound to.

Example:

<input type="text" class="jqTextboxList" id="mylist" />
<script>
jQuery(function($) {
  $("#mylist").bind("SelectValue", function(value) {
    ...
  });
});
</script>
