[dev] Framework :: Browser optgroup feature

[jvandal at infoteck.qc.ca]

Hi,

I've add a new feature to the Browser class. It the OPTGROUP (HTML 4.0) element. Here is a short description of this form tag :


The OPTGROUP element allows authors to group selection list choices into a hierarchy. This is particularly helpful to non-visual user agents when large numbers of options are available to choose from. Possible rendering of this element could be a collapsible hierarchy list of OPTION element content or some presentation conveying the hierarchy relationship of the OPTION contents. Browsers not supporting this element will "see" only a traditional flat list of OPTION elements. The LABEL attribute for this element is used to provide shorter labels for the nodes of the hierarchical menus. 
I want tu use this feature in some <select> list so if the browser support the optgroup feature, it will show the list like :

My Calendar
Shared Calendars
    Michael Smith
    Susan Smith
    Howard Smith
Remote Calendars
    Robert Smith

If no support is available, use the current way:

+ My Calendar
Shared Calendars:
 + Michael Smith
 + Susan Smith
 + Howard Smith
Remote Calendars:
 + Robert Smith

    
Example of future use (patch will follow):

<select NAME="calendars">
<option LABEL="My Calendar" VALUE="calendar">My Calendar
<optgroup LABEL="Shared Calendars">
    <option VALUE="michael">Michael Smith
    <option VALUE="susan">Susan Smith
    <option VALUE="howard">Howard Smith
</optgroup>
<optgroup LABEL="Remote Calendars">
    <option VALUE="robert">Robert Smith
</optgroup>
</select>
