Currenlty on my editor I can wrap text in any tag. But I am un able to unwarp the selected text also.

My question is lets say if I select / highlight text which is wrapped in '<b>' something '</b>' and then I go and click on the bold button again how is it possiable to remove/unwrap those tags?

$(document).ready(function() {

    // tooltips on hover
    $('[data-toggle=\'tooltip\']').tooltip({container: 'body', html: true});

    // Makes tooltips work on ajax generated content
    $(document).ajaxStop(function() {
        $('[data-toggle=\'tooltip\']').tooltip({container: 'body'});
    });

    $('[data-toggle=\'tooltip\']').on('remove', function() {
        $(this).tooltip('destroy');
    });
