Core options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-style="" or data-selected-text-format="count".

Events

Bootstrap-select exposes a few events for hooking into select functionality.

hide.bs.select, hidden.bs.select, show.bs.select, and shown.bs.select all have a relatedTarget property, whose value is the toggling anchor element.

Name Type Default Description
actionsBox boolean false

When set to true, adds two buttons to the top of the dropdown menu (Select All & Deselect All).
container string | false false

When set to a string, appends the select to a specific element or selector, e.g., container: 'body' | '.main-body'
countSelectedText string | function function

Sets the format for the text displayed when selectedTextFormat is count or count > #. {0} is the selected amount. {1} is total available for selection.

When set to a function, the first parameter is the number of selected options, and the second is the total number of options. The function must return a string.
deselectAllText string 'Deselect All'

The text on the button that deselects all options when actionsBox is enabled.
dropdownAlignRight boolean | 'auto' false

Align the menu to the right instead of the left. If set to 'auto', the menu will automatically align right if there isn't room for the menu's full width when aligned to the left.
dropupAuto boolean true

checks to see which has more room, above or below. If the dropup has enough room to fully open normally, but there is more room above, the dropup still opens normally. Otherwise, it becomes a dropup. If dropupAuto is set to false, dropups must be called manually.
header string false

adds a header to the top of the menu; includes a close button by default
hideDisabled boolean false

removes disabled options and optgroups from the menu data-hide-disabled: true
iconBase string 'glyphicon'

Set the base to use a different icon font instead of Glyphicons. If changing iconBase, you might also want to change tickIcon, in case the new icon font uses a different naming scheme.
liveSearch boolean false

When set to true, adds a search box to the top of the selectpicker dropdown.
liveSearchNormalize boolean false

Setting liveSearchNormalize to true allows for accent-insensitive searching.
liveSearchPlaceholder string null

When set to a string, a placeholder attribute equal to the string will be added to the liveSearch input.
liveSearchStyle string 'contains'

When set to 'contains', searching will reveal options that contain the searched text. For example, searching for pl with return both Apple, Plum, and Plantain. When set to 'startsWith', searching for pl will return only Plum and Plantain.
maxOptions integer | false false

When set to an integer and in a multi-select, the number of selected options cannot exceed the given value.

This option can also exist as a data-attribute for an <optgroup>, in which case it only applies to that <optgroup>.
maxOptionsText string | array | function function

The text that is displayed when maxOptions is enabled and the maximum number of options for the given scenario have been selected.

If a function is used, it must return an array. array[0] is the text used when maxOptions is applied to the entire select element. array[1] is the text used when maxOptions is used on an optgroup. If a string is used, the same text is used for both the element and the optgroup.

multipleSeparator string ', '

noneSelectedText string 'Nothing selected'

The text on the button that selects all options when actionsBox is enabled.
selectedTextFormat 'values' | 'static' | 'count' | 'count > x' (where x is an integer) 'values'

Specifies how the selection is displayed with a multiple select.

'values' displays a list of the selected options (separated by multipleSeparator. 'static' simply displays the select element's title. 'count' displays the total number of selected options. 'count > x' behaves like 'values' until the number of selected options is greater than x; after that, it behaves like 'count'.

size 'auto' | integer | false 'auto'

When set to 'auto', the menu always opens up to show as many items as the window will allow without being cut off.

When set to an integer, the menu will show the given number of items, even if the dropdown is cut off.

When set to false, the menu will always show all items.
style string | null null

When set to a string, add the value to the button's style.
tickIcon string 'glyphicon-ok'

Set which icon to use to display as the "tick" next to selected options.
