/**
* Toggle Inputfield
*
* An Inputfield for handling an on/off toggle that maintains a boolean value (or null when no selection).
* This provides an alternative to a single checkbox field.
*
* ProcessWire 3.x, Copyright 2020 by Ryan Cramer
* https://processwire.com
*
* API usage example
* ~~~~~~
* // Default behavior displays toggle of "Yes" and "No":
* $f = $modules->get('InputfieldToggle');
* $f->attr('name', 'test_toggle_field');
* $f->label = 'Do you like toggle fields?';
*
* // Optionally make it show "On" and "Off" (rather than "Yes" and "No"):
* $f->labelType = InputfieldToggle::labelTypeOn;
*
* // Optionally set custom labels:
* $f->labelType = InputfieldToggle::labelTypeCustom;
* $f->yesLabel = 'Yes please';
* $f->noLabel = 'No thanks';
*
* // Optionally add an "other" option with label "Not sure":
* $f->useOther = true;
* $f->otherLabel = 'Not sure';
*
* // Set the value: 0=No, 1=Yes, 2=Other, or blank string '' for no selection (Unknown)
* $f->val(1);
*
* // Optionally set to use radio buttons rather than toggle buttons:
* $f->inputfieldClass = 'InputfieldRadios';
*
* // Remember to add to your InputfieldForm, InputfieldWrapper or InputfieldFieldset:
* $form->add($f);
* echo $form->render();
* ~~~~~~
*
* @property int|string $value Integer value when selection is made or blank string when no selection (0=No, 1=Yes, 2=Other, ''=Unknown)
* @property int $labelType Label type to use, see the labelType constants (default=labelTypeYes)
* @property int $valueType Type of value for methods that ask for it (use one of the valueType constants)
* @property string $yesLabel Custom yes/on label
* @property string $noLabel Custom no/off label
* @property string $otherLabel Custom label for optional other value Label to use for "other" option
* @property int|bool $useReverse Reverse the order of the Yes/No options? (default=false)
* @property int|bool $useOther Use the "other" option? (default=false)
* @property bool|int $useVertical Use vertically oriented radio buttons? Applies only if $inputfieldClass is 'InputfieldRadios' (default=false)
* @property bool|int $useDeselect Allow radios or toggles to be de-selected, enabling possibility of no-selection? (default=false)
* @property string $defaultOption Default selected value of 'no', 'yes', 'other' or 'none' (default='none')
* @property string $inputfieldClass Inputfield class to use or blank for this toggle buttons (default='')
*
* @method InputfieldSelect|InputfieldRadios getInputfield()
