#### Forms - Dual Listboxes

Statistics Invoices Schedule

##### Basic example

The dual listbox is created from a select multiple by calling `.bootstrapDualListbox(settings);` on a selector. The selector can be any element, not just selects. When the method is called on a selector other than a select, then all select childrens are converted into dual list boxes. This example demonstrates `single` option selection.

##### Multiple selection

Multiple selection example. By default, only single selection is allowed: once you click on the option, it automatically moves to another box. To disable single selection and turn on multiple, set `moveOnSelect` option to `false` in plugin configuration. Defaults to `true` and this option is forced to `true` on the Android browser.

##### Filtered results

The following example demonstrates initialization of the dual listbox with a filter for the non selected elements, currently from 7 to 12. This can be applied only if `showFilterInputs` is set to `true`. Using `selectedFilter` option, listbox will filter selected elements only. You can use "Display all" button as a filter reset.

##### Disable filter

The following example demonstrates listbox with disabled filter input. By default, filter input field is always visible, unless `showFilterInputs` option is set to `false`. Please note: if false, all additional filter options such as filtered results will be disabled, but all plugin options related to selects will remain available.

##### Control boxes height

This example demonstrates ability to change the minimal height of the generated dual listbox. Default listbox height is `200px`, in this example the height is increased up to `300px` using `selectorMinimalHeight` option. This value is applied to the list itself, but not to the whole container with other elements.

##### Custom text support

This example demonstrates how custom text or language can be used in dual listbox controls. All these text labels and placeholders are fully editable through specified options, such as: `infoText`, `infoTextFiltered`, `infoTextEmpty`, `filterPlaceHolder` etc.

##### Adding options dynamically

The options must be added to/removed from the original select. Note that the `bootstrapDualListbox.refresh` event must be triggered on it after manipulating the options. If there are some highlighted options in the lists, then triggering the `bootstrapDualListbox.refresh` event with the optional `true` parameter results the highlights to be removed.
