The configuration includes: +// +// * a global default state ('defaultInstanceState') for all instance +// lists. The possible values for the global default are "collapsed" +// and "expanded". +// +// * a global boolean option ('rememberToggles') to remember which +// specific instance lists are not in the default state (e.g. which +// instance lists are expanded when the default is "collapsed"). +// +// * a local / per-page record of which specific instance lists are +// not in the default state, when the global option +// ('rememberToggles') to remember this info is enabled. +// +// The UI consists of an Instances menu with buttons for expanding and +// collapsing all instance lists in the current module, a checkbox for +// setting the global default state, and a checkbox to enable +// remembering which instance lists are not in the global default +// state. Also, each instance list on each module page has buttons for +// collapsing and expanding. +// +// The logic of the UI is as follows: +// +// * setting the global default state erases any record of which +// specific instances are in the non-default state, and collapses or +// expands all instance lists on the current page to be in the +// global default state. +// +// * changing boolean option for remembering which specific instance +// lists are not in the default state erases any existing record of +// which instances are not in the default state across all pages, +// and updates the record for the current page when the option is +// set to true. No collapsing or expanding is done. +// +// * toggling the collapse/expand state of a specific instance list +// causes the state of that specific instance list to be recorded in +// the persisted configuration iff the new state of that specific +// instance list is different from the global default state, and the +// option to remember instance list states is enabled. There are two +// ways to toggle the collapse/expand state of a specific instance, +// by clicking its collapse/expand button, and by clicking the +// "collapse all" or "expand all" button in the Instances menu. +// +// This file also implements an association between elements (with +// class "details-toggle" and "details-toggle-control") that can be +// clicked to expand/collapse <details> elements, and the details +// elements themselves. Note that this covers both <details> elements +// that list instances -- what the above explained UI and logic is +// concerned with -- and details about individual instances themselves +// -- which the above is not concerend with.
