• iconRemove, defaults to oi-arrow-thick-left, sets the class for the remove icon.

Methods

You can modify the behavior and aspect of the dual listbox by calling its methods, all of which accept a value and a refresh option. The value determines the new parameter value, while refresh (optional, defaults to false) tells whether to update the plugin UI or not.

To call methods on the dual listbox instance, use the following syntax:

$(selector).bootstrapDualListbox(methodName, parameter);

Note: when making multiple chained calls to the plugin, set refresh to true to the last call only, in order to make a unique UI change; alternatively, you can also call the refresh method as your last one.

Here are the available methods:

• setBootstrap2Compatible(value, refresh) to change the bootstrap2Compatible parameter.
• setBootstrap3Compatible(value, refresh) to change the bootstrap3Compatible parameter.
• setFilterTextClear(value, refresh) to change the filterTextClear parameter.
• setFilterPlaceHolder(value, refresh) to change the filterPlaceHolder parameter.
• setMoveSelectedLabel(value, refresh) to change the moveSelectedLabel parameter.
• setMoveAllLabel(value, refresh) to change the moveAllLabel parameter.
• setRemoveSelectedLabel(value, refresh) to change the removeSelectedLabel parameter.
• setRemoveAllLabel(value, refresh) to change the removeAllLabel parameter.
• setMoveOnSelect(value, refresh) to change the moveOnSelect parameter.
• setMoveOnDoubleClick(value, refresh) to change the moveOnDoubleClick parameter.
• setPreserveSelectionOnMove(value, refresh) to change the preserveSelectionOnMove parameter.
• setSelectedListLabel(value, refresh) to change the selectedListLabel parameter.
• setNonSelectedListLabel(value, refresh) to change the nonSelectedListLabel parameter.
• setHelperSelectNamePostfix(value, refresh) to change the helperSelectNamePostfix parameter.
• setSelectOrMinimalHeight(value, refresh) to change the selectorMinimalHeight parameter.
• setShowFilterInputs(value, refresh) to change the showFilterInputs parameter.
• setNonSelectedFilter(value, refresh) to change the nonSelectedFilter parameter.
• setSelectedFilter(value, refresh) to change the selectedFilter parameter.
• setInfoText(value, refresh) to change the infoText parameter.
• setInfoTextFiltered(value, refresh) to change the infoTextFiltered parameter.
• setInfoTextEmpty(value, refresh) to change the infoTextEmpty parameter.
• setFilterOnValues(value, refresh) to change the filterOnValues parameter.

Furthermore, you can call:

• refresh() or trigger the bootstrapDualListbox.refresh event to update the plugin element UI.
• destroy() to restore the original select element and delete the plugin element.
• getContainer() to get the container element.
