Overview
Conditional subpanels are subpanels that are only displayed if the value of a specified boolean preference is true. This functionality allows adjusters to be displayed or hidden based on the setting of another on/off adjuster.
The relationship between the controlling boolean preference and its dependent subpanels is defined in the panels property of the groups block. The panels property has one required property: always, which is an array of keys defining panels which should always be displayed. Other properties use a preference name as a key; the preference must be a boolean preference that is in a subpanel in the 'always' list. The value is an array of panel keys that should be displayed only if the specified preference is true.
"panels": {
always: [<list of subpanels to always include in this composite panel; must contain at least one>], // required
<pref.name>: [<list of subpanels to display only when this pref is on>], // optional
<pref.name>: [<list of subpanels to display only when this pref is on>],
...,
}
Notes:
- A conditional subpanel must contain ONLY ONE adjuster.
- A controlling preference MUST be a boolean.
- The
pref.name
keys MUST refer to a preference referenced in the always
property. - Not every
always
panel must control a conditional subpanel. - Panel definitions are the same for controlling subpanels, conditional subpanels and regular subpanels; there is no difference.
