// example:
$("#multiselect").multiselect("method_name");

---

open

Opens the menu.

---

close

Closes the menu.

---

refresh

Reloads the checkbox menu. If you're dynamically adding/removing option tags on the original select via AJAX or DOM manipulation methods, call refresh to reflect the changes in the widget.

Parameter:

init If true, the refresh event is not triggered.

---

update

Updates the button text to reflect the number of current selections or the list of current selections, if the selectedList option is set.

Parameter:

isDefault If true, the button text is also set as the default for the button to prevent form resets from reverting the text to the prior default value.

---

resync

disable

Disable the entire widget.

enable
