DESCRIPTION

This tag can display content depending on current (or provided) page name. It is most directly useful for creating menu bars (although other uses are not excluded).

The content between the [selected][/selected] tags will be displayed if the name of the current page (MV_PAGE variable, or your custom current argument) matches the page parameter.

The default content (one outside of [select] tags) will be displayed when there is no match.

BEHAVIOR

This tag appears to be affected by, or affects, the following:
Global Variables: MV_PAGE

EXAMPLES

Example: Create 3-button menubar

Create three different pages, page1.html, page2.html and page3.html, each with the identical content:

<table><tr>

[bar-button page=page1]
<td><a href="[area page1]">PAGE-1</a></td>
[selected]
<td bgcolor="red"><a href="[area page1]"><b>PAGE-1-selected</b></a></td>
[/selected]
[/bar-button]

[bar-button page=page2]
<td><a href="[area page2]">PAGE-2</a></td>
[selected]
<td bgcolor="red"><a href="[area page2]"><b>PAGE-2-selected</b></a></td>
[/selected]
[/bar-button]

[bar-button page=page3]
<td><a href="[area page3]">PAGE-3</a></td>
[selected]
<td bgcolor="red"><a href="[area page3]"><b>PAGE-3-selected</b></a></td>
[/selected]
[/bar-button]

</tr></table>
