Hmmm having a dependency on ngSanitize is not really good to me since I don't want to add a requirement that will be useless for 99% of the slider users.

Actually, when implementing #251, I didn't think about this issue but the string passed to html() should also be sanitized to avoid exploits.

I need to think more about it...

I agree that sanitizing is generally a good idea.

For my case, there actually is an easy fix. I copied the default template, did my fix mentioned above, and used rz-slider-tpl-url to use my custom template.

Not optimal, but definitely working.

well, you could use $sce.trustAsHtml(html) and ng-bind-html in the template? so no need to use ngSanitize, right?

or use a filter like
app.filter('unsafe', function($sce) { return $sce.trustAsHtml; });

Indeed, but in order to use $sce, angular-sanitize.js has to be included and I don't want to force all the users to include it when they don't use html ticks.

Not being able to use html ticks is a real buzzkill for me

I understand but I couldn't find a solution so far. If you have something to suggest, I would be grateful! ;)

I used @saus's suggestion for now. I override the template and use ng-bind-html with ngSantize to get the desired result.

Yes this is a good workaround, I should probably document the template overriding so other users can use it.

Yeah, I had to go in the source to find that option. Documenting would be a good idea, maybe even add a example with ng-bind-html

well seems like the only option, if you dont want any dependencies. but to be honest, using ng-bind-html and custom template will do. However, as @boboldehampsink stated, a small hint in the documentation, would be good.

Documentation added about rz-slider-tpl-url. Still need to add an example.

Demo added in http://angular-slider.github.io/angularjs-slider. Check the "Slider with custom template to use HTML formatting for ticks" part. ;)
