Yes, I've found it now. Patrick, I suggest you change the instructions in the Readme.txt file that indicates that "Tab display" will appear in the "Activities" menu.
I've seen this module in the past. I think the new version is improved. Well done.
When creating an instance of a Tab Display I encountered an error...
Notice: Undefined index: group in D:\xampplite\htdocs\moodle\lib\form\advcheckbox.php on line 47
...which relates to the addElement() call at line 359 in mod_form.php, which is missing its second last argument. I changed this too...
$mform->addElement('advcheckbox', 'displaymenu', get_string('displaymenuagree', 'tab'),null, array('group' => 1),array('0','1'));
...which removed the error. For details see...
I thought the CSS control was unnecessary on the config page. I can see that institutions might want to change the stylesheet at a site level. Perhaps this control could be moved to a global config page. It would be even better if the module could draw on the theme colour scheme for tabs. To be honest, I'm not sure why you need the YUI library just to hide and reveal some divs.
It was not clear to me what the "Tab display menu" section was for at first. I tried this out to discover that it can show a menu when there are more than one Tab Display modules. Perhaps some more obvious wording such as "Show menu for multiple tab display instances" would help make this obvious. I had no idea what to put in the box labeled "Tab display activity order within menu". Is there some coding system needed to prescribe the order that tab displays will appear? Is there some way this could be simplified? Certainly some help files could assist with these settings. I often imagine the mass of technically unskilled teachers using Moodle when considering what settings are really needed and what help these people will need to set them. Often I think developers include settings because they can, when in fact some defaults would suffice, and would simplify the configuration.
Without a "Tab display menu" the tabs butted up against my the navigation menu. I would have liked some spacing in between. When I added a menu there was a nice spacing below the page navigation.
The default colour scheme of black on blue could make text difficult to read for people with visual impairments who require more contrast. This may prevent the module from being used at some institutions where accessibility compliance is required. In the menu, the background was blue and the link text was blue also, which would be very hard for some people to read.
All in all, I think this is a good module. Simpler than the Book module, but still able to present information in a structured way.
Well done Patrick. Keep up the good work.
