> endLevel's as relative to active page through new a attribute
> ------------------------------------------------------------------------------------------------------------------------------------
>
> Key: MAGNOLIA-2053
> URL: http://jira.magnolia.info/browse/MAGNOLIA-2053
> Project: Magnolia
> Issue Type: Improvement
> Components: taglibs
> Affects Versions: 3.5.4
> Reporter: Ryan Gardner
> Assignee: Gregory Joseph
> Priority: Minor
> Fix For: 3.6.2
>
> Attachments: AddRelativeModeToSimpleNav.patch, levelhandling2_.patch
>
>
> In some cases, it is desirable to have a SimpleNavigation that always shows
> the children of a given page, or that always shows the siblings of a given
> page. SimpleNavigation currently specifies the startLevel and endLevel in
> absolute terms.
> The attached patch adds an optional attribute to the SimpleNavigation tag
> that allows you to specifiy the way the levels are handled. I called it
> "levelHandlingMode" for lack of a better name, and when it is set to
> "relative" the behavior is changed slightly. At the start of the doEndTag, it
> does this:
> if (this.levelHandlingMode.equals(LEVEL_MODE_RELATIVE)) {
> this.startLevel += activePageLevel;
> this.endLevel += activePageLevel;
> }
> This simple change at the beginning of the doEndTag will allow you to specify
> negative values for the start value or end value, and have it work
> appropriately.
> I've tested it for the use case that I wanted it to work for, and it works
> properly... and, most importantly, it doesn't break any existing
> functionality.
