### setChoices(choices, value, label, replaceChoices);
|
||||
**Input types affected:** `select-one`, `select-multiple`
|
||||
|
||||
**Usage:** Set choices of select input via an array of objects, a value name and a label name. This behaves the same as passing items via the `choices` option but can be called after initialising Choices. This can also be used to add groups of choices (see example 2); Optionally pass a true `replaceChoices` value to remove any existing choices. Optionally pass a `customProperties` object to add additional data to your choices (useful when searching/filtering etc).

Passing an empty array as the first parameter, and a true `replaceChoices` is the same as calling `clearChoices` (see below).
