Fallback for PDF generation

[bjornpiltz]

It would be nice if sphinx_tabs had a useful fallback for pdf generation. ATM it renders like this:

Apples

Pears

Oranges

Apples are green, or sometimes red.

Pears are green.

Oranges are orange.

It would be swell if it looked like this:

Apples

Apples are green, or sometimes red.

Pears

Pears are green.

Oranges

Oranges are orange.

I just created a workaound for this. I modified the tabs.py

class TabsDirective(Directive):
    """ Top-level tabs directive """

    has_content = True

    def run(self):
        """ Parse a tabs directive """
        self.assert_has_content()
        env = self.state.document.settings.env

        node = nodes.container()
        node['classes'] = ['sphinx-tabs']

        env.temp_data['tab_ids'] = []
        env.temp_data['tab_titles'] = []
        env.temp_data['is_first_tab'] = True

        # render tab-titles only if not latex

            tabs_node.tagname = 'div'

            classes = 'ui top attached tabular menu sphinx-menu'
