// Using parent and child options where parent is selected to reveal child options
|
|||
|
|
// -------------------------------------------------------------------------------
|
|||
|
|
// 1. Parent option(s) must have a class attribute of 'asmParent'. While optional, I also recommend the label have an
|
|||
|
|
// ellipsis or something to indicate it is a parent:
|
|||
|
|
//
|
|||
|
|
// <option value='foo' class='asmParent'>Foo …</option>
|
|||
|
|
//
|
|||
|
|
// 2. Child options must come immediately after parent and have a 'data-asmParent' attribute containing 'value' attribute
|
|||
|
|
// of parent. While optional, I also recommend the child option include both parent and child label so that the
|
|||
|
|
// relationship remains clear even after selection, i.e. “Foo > Bar” or “Foo: Bar” or similar:
|
|||
|
|
//
|
|||
|
|
// <option value='bar' data-asmParent='foo'>Foo: Bar</option>
|
|||
|
|
//
|
|||
|
|
// Please Note:
|
|||
|
|
// • Selecting a parent option does not modify the value of the selection, it only reveals more selectable options.
|
|||
|
|
// • Up to two levels of parent/child options are supported (more levels may also work but have not been attempted).
|
|||
|
|
// • The options below define the settings for parent/child options (most will want to leave as-is):
|
|||
|
|
|
|||
|
|
optionParentClass: 'asmParent', // Class you will assign to a parent item that has one or more child items
|
|||
|
|
optionParentIcon: '⬇', // UTF-8 down-pointing arrow icon added to select parent options, indicating more options to select
|
|||
|
|
optionChildAttr: 'data-asmParent', // Attribute you will add to child items with its value pointing to the option.asmParent’s value attribute
|
|||
|
|
optionParentOpenClass: 'asmParentOpen', // Assigned automatically: Class for a parent option that has its children visible
|
|||
|
|
optionChildClass: 'asmChild', // Assigned automatically: Class for an option that has a parent option
