31:T641,# Input presets The `presetMenu` function allows setting an input form with values chosen from a list of named presets. Usage: >`presetMenu (` _form_, _presets_, _options_ `)` where > _form_ is an input form, typically built with `Inputs.form`. > > _presets_ is an object containing a number of named presets, i.e., an object of the form > > { name1 : preset#1,
> > name2 : preset#2,
> > ...
> > }
> >
> > where each preset is an object with the same items as _form_ > > _options_ is an object which controls the behavior of the presetMenu, namely: > > - `label:` _string_. Sets the menu label. Default: "presets". > - `initialPreset:` _name_. Sets preset _name_ as the initial value of the input form. Default : `null` (no initial preset). > - `editable:` _boolean_. If true, the current preset is interactively changed to the value of the input form. Otherwise, changes in the form will not alter the original presets, although new presets can still be created and old presets removed. Default: _true_. > - `alwaysSelected:` _boolean_. If true, one of the presets is always selected. This means that at least one preset must be provided. Useful only if `editable` is true. Default: _false_. > - `callback:` _function_. If specified, _function_ is called for every change in the form. The presetMenu is itself an input that mirrors the value of `_form_`. Additionally, it provides the following methods: - presetMenu._getCurrent()_ returns the name of the currently selected preset. - presetMenu._getPresets()_ returns the presets object.
