HTML Validation: Ability to ignore custom htm tags (e.g. <ion-*>) ----------------------------------------------------------------- Key: JBIDE-18724 URL: https://issues.jboss.org/browse/JBIDE-18724 Project: Tools (JBoss Tools) Issue Type: Feature Request Components: jsp/jsf/xml/html source editing, upstream Reporter: Victor Rubezhny Assignee: Victor Rubezhny Labels: new_and_noteworthy Fix For: 4.2.3.Beta1 Attachments: validation.png WTP HTML validator marks any custom html tags as unknown. It's possible to disable this validation at all: Window->Preferences->Web->HTML Files->Validation ==> Set Elements -> Unknown tag name severity to "Ignore": !00001262.png! But it would be useful to have ability to make HTML validator ignore some particular tags only. I suggest to contribute a patch to WTP to fix it. We have already did it for attributes, so lets do it for tags too: - New preferences with a list of ignored tags (a mask can be used) - A new preference page to set these preferences - QuickFix for validation problem which will add the tag name/mask to this list/preferences - Extension in our angular/ionic plugin which will disable validation for <ion-*> tags. I've filed it to bugzilla - https://bugs.eclipse.org/bugs/show_bug.cgi?id=444545 but we have to provide a patch for it if we want to have it done ;)
