-/*
- * Inspector control
- *
- * Manages properties of inspectable controls.
- *
- * Data attributes:
- * - data-inspectable - makes a control inspectable.
- * - data-inspector-title - title for the inspector popup
- * - data-inspector-description - optional description for the inspector popup
- * - data-inspector-class - PHP class name of the inspectable object. Required for drop-down
- * fields with dynamic options.
- * - data-inspector-css-class - CSS class name to apply to the Inspector container element.
- * - data-inspector-container - specifies a CSS selector for the inspector container. The default container
- * is the document body. The container element should be relative positioned. The 'self' container value
- * allows to inject the inspector to the inspectable element.
- * - data-inspector-offset - offset in pixels to add to the calculated position, to make the position more "random"
- * - data-inspector-placement - top | bottom | left | right. The placement could automatically be changed
- if the popover doesn't fit into the desired position.
- * - data-inspector-fallback-placement - The placement to use if the default placement
- * and all other possible placements do not work. The default value is "bottom".
- * - data-inspector-config - Configuration of the inspector fields as an array in the JSON format.
- * Each element in the array is an object with the following properties:
- * - property
- * - title
- * - group (optional)
- * - type (currently supported types are: string, checkbox, dropdown)
- * - description (optional)
- * - validationPattern (regex pattern for for validating the value, supported by the text editor)
- * - validationMessage (a message to display if the validation fails)
- * - placeholder - placholder text, for text and dropdown properties
- * - default - default value
- * - depends - a list of properties the property depend on, for dropdown lists
- * - options - an option list for dropdown lists, optional. If not provided the options are loaded with AJAX.
- * - showExternalParam - specifies the visibility of the external parameter feature for the property. Default: true.
- * Example of the configuration string (a single property):
- * [{"property":"max-width","title":"Max width","type":"string"}]
- *
- * The Inspector requires the inspectable element to contain a hidden input element with the attribute "data-inspector-values".
- * The inspector uses this field to read and write field values. The field value is a JSON string, an object with keys matching property
- * names and values matching property values.
- *
- * Any HTML element that wraps the inspectable element can have the data-inspector-external-parameters property that enables the external
- * parameters support. External parameters saved with the special syntax {{ paramName }}. The external parameter feature can be toggled
- * on per-property basis with the showExternalParam option, visible by default.
- *
- * Events
- * - change - the event is triggered on the inspectable element when it's properties are updated.
- * - showing.oc.inspector - triggered before the Inspector is displayed. Allows to cancel the action with e.preventDefault()
- * - hiding.oc.inspector - triggered before the Inspector is hidden. Allows to cancel the action with e.preventDefault()
- * - hidden.oc.inspector - triggered after the Inspector is hidden.
- *
- * Dependences:
- * - october.popover.js
