Martin Grigorov resolved WICKET-1785. ------------------------------------- Resolution: Duplicate Improved with WICKET-2674 (Wicket 1.5.6+). > Ability to add attributes to drop-down-list (select) options > ------------------------------------------------------------ > > Key: WICKET-1785 > URL: https://issues.apache.org/jira/browse/WICKET-1785 > Project: Wicket > Issue Type: Improvement > Components: wicket > Affects Versions: 1.4-M3 > Reporter: Martin Makundi > Priority: Minor > Original Estimate: 5m > Remaining Estimate: 5m > > Time-after-time, there is need to style your select options in a > DropDownChoice component. For example, the different options need to have > different background colour, or something. > This can be accomplished using Select/SelectOption, but here you are required > to re-implement all the intelligence already built into the > dropdownchoice/listchoice component (automatic notnull and localization, for > example). > How could we leverage the existing functionality of the DropDownChoice but > enhance it with the ability to parametrize option attributes individually? > Our suggestion is that we refactor suitable hooks into the rendering phase of > the xxChoice components, i.e., a method along the lines of "String > getOptionAttributes(T t)" to be called, during the render phase of a > DropDownChoice (in order to add attributes for the option tag). > With this kind of impementation it would then be easier for anybody to > 'sugarcoat' their DropDownChoice without breaking the existing > inplementations. For example, one way to use it would be to just add a > getDispayStyle method into your implementation of the IChoiceRenderer, and > implement a respective check in your overriding "getOptionAttributes" -method: > MyDropDownChoice extends DropDownChoice() { > @Override > protected String getOptionAttributes(T t) { > if (renderer instanceof MyChoiceRenderer) { > ... and sugarcoat my option ... > } > } > } > More discussion can be found at: > http://www.nabble.com/color-code-options-in-drop-down-choice-tp16964792p18909328.html -- This message is automatically generated by JIRA.
