             Summary: Disable escaping of html tag attributes
                 Key: WICKET-5242
                 URL: https://issues.apache.org/jira/browse/WICKET-5242
             Project: Wicket
          Issue Type: Improvement
          Components: wicket
    Affects Versions: 6.7.0
            Reporter: Bertrand Guay-Paquet


Currently, all component tag attributes are escaped.With html5 data- attributes, much more values can be considered valid depending on the tag attribute and some should not be escaped.

For example, bootstrap tooltips use the "data-title" attribute to set the content of a tooltip. Using Wicket's tag attributes, it's not possible to set the value "<b>hello world</b>" as the data-title since it is escaped.

ComponentTag#writeOutput() is the method which calls Strings.escapeMarkup(value); and escapes tag values. This is called by Component#renderComponentTag().

There should be a way to disable component tag escaping either per-tag or per-component.
