- // description
- // An enhanced version of the HTML SELECT tag, populated dynamically. It works
- // very nicely with very large data sets because it can load and page data as needed.
- // It also resembles ComboBox, but does not allow values outside of the provided ones.
- //
- // Similar features:
- // - There is a drop down list of possible values.
- // - You can only enter a value from the drop down list. (You can't
- // enter an arbitrary value.)
- // - The value submitted with the form is the hidden value (ex: CA),
- // not the displayed value a.k.a. label (ex: California)
- //
- // Enhancements over plain HTML version:
- // - If you type in some text then it will filter down the list of
- // possible values in the drop down list.
- // - List can be specified either as a static list or via a javascript
- // function (that can get the list from a server)
- //
- // searchAttr: String
- // Searches pattern match against this field
- //
- // labelAttr: String
- // Optional. The text that actually appears in the drop down.
- // If not specified, the searchAttr text is used instead.
- labelAttr: "",

- // labelType: String
- // "html" or "text"
