I've bitten the bullet and tried my hand at creating a (sort of) plugin, ie adding a button to my editor. What I wanted to achieve was something like this, where a user could add an explanation about a word if it were difficult. (The site is for language learners so articles are supposed to be in easy language.)

Here's the code from my button:

<a href='#' title='{option}' data-ipsTooltip>{content}</a>

But what I'm getting is this:

and the reason is because my data-ipsTooltip isn't present:

If I change the code in my browser, then everything is fine:

So the problem centres on data-ipsTooltip being stripped. Why is that? And how can I work around it?

It's not just my data-ipsToolbar. I've just tried to add a CSS class and that got stripped too. Why is that? More importantly, how can I work around it?

The editor is stripping everything what's not whitelisted because of security reasons.

You can whitelist the css and js stuff in your ACP => Customization => Editor Settings

Thank you, Daniel. I've got CSS working but am not having any luck with JS. I tried entering "data-ipsTooltip" in the JS field, since that seemed the likeliest thing. Do I need to enter it differently?

you may need to look into ckeditor config.allowedContent (just do a search on the Web for it)

basically, you will have to edit your ckeditor config file

The setting lets you specify additional allowed data controllers (e.g. values that can be used in data-controller).

You will need to create a plugin on \IPS\Text\Parser against the _htmlPurifierModifyHtmlDefinition() method to allow any new attributes. You'll probably be looking at something like

	/**
	 * Customize HTML Purifier HTML Definition
	 *
	 * @param	HTMLPurifier_HTMLDefinition	$def	The definition
	 * @return	void
	 */
	protected function _htmlPurifierModifyHtmlDefinition( \HTMLPurifier_HTMLDefinition $def )
	{
		parent::_htmlPurifierModifyHtmlDefinition( $def );

		/* Allow the data-ipstooltip attribute on 'a' tags */
		$def->addAttribute( 'a', 'data-ipstooltip', 'Bool' );
	}

I think I'll probably need to have somebody else looking at that! My first attempt at a "plugin" (ie creating a simple button) seems to have morphed into actually needing a plugin. 

Thank you for the push into the right direction 🙂
