32 // optionheader provides a collapsible toolbar for buttons and
33 // segmented controls directly under the title bar. It
34 // wraps a jQuery Mobile grid in a collapsible container; clicking
35 // on the container, or on one of the buttons inside the container,
38 // To add an option header to a page, mark up the header with a
39 // data-role="optionheader" attribute, as shown in this example:
41 // <div data-role="header">
42 // <h1>Option header - 3 buttons example</h1>
43 // <div data-role="optionheader">
44 // <div class="ui-grid-b">
45 // <div class="ui-block-a"><a data-role="button">Previous</a></div>
46 // <div class="ui-block-b"><a data-role="button">Cancel</a></div>
47 // <div class="ui-block-c"><a data-role="button">Next</a></div>
52 // The optionheader can also be used inline (e.g. in a content block or
55 // Alternatively, use $('...').optionheader() to apply programmatically.
57 // The grid inside the optionheader should be marked up as for
58 // a standard jQuery Mobile grid. (The widget has been tested with one
59 // or two rows of 2-4 columns each.)
61 // Note that if you use this with fixed headers, you may find that
62 // expanding the option header increases the page size so that scrollbars
63 // appear (jQuery Mobile's own collapsible content areas cause the
64 // same issue). You can alleviate this somewhat by calling the show() method
65 // on the page toolbars each time the size of the header changes.
67 // The widget is configurable via a data-options attribute on the same
68 // div as the data-role="optionheader" attribute, e.g.
70 // <div data-role="header">
71 // <h1>Option header - configured</h1>
72 // <div data-role="optionheader" data-options='{"collapsed":true, "duration":1.5}'>
73 // <div class="ui-grid-b">
74 // <div class="ui-block-a"><a data-role="button">Previous</a></div>
75 // <div class="ui-block-b"><a data-role="button">Cancel</a></div>
76 // <div class="ui-block-c"><a data-role="button">Next</a></div>
81 // Options can also be set with $(...).optionheader('option', 'name', value).
82 // However, if you do this, you'll need to call $(...).optionheader('refresh')
83 // afterwards for the new values to take effect (note that optionheader()
84 // can be applied multiple times to an element without side effects).
86 // See below for the available options.
88 // Theme: by default, gets a 'b' swatch; override with data-theme="X"
91 // Options (can be set with a data-options attribute):
93 // {Boolean} [showIndicator=true] Set to true (the default) to show
94 // the upward-pointing arrow indicator on top of the title bar.
95 // {Boolean} [startCollapsed=false] Sets the appearance when the option
96 // header is first displayed; defaults to false (i.e. show the header
97 // expanded on first draw). NB setting this option later has no
98 // effect: use collapse() to collapse a widget which is already
100 // {Boolean} [expandable=true] Sets whether the header will expand
101 // in response to clicks; default = true.
102 // {Float} [duration=0.25] Duration of the expand/collapse animation.
104 // Methods (see below for docs):
112 // expand: Triggered when the option header is expanded
113 // collapse: Triggered when the option header is collapsed
