Description of the task : https://dev.tiki.org/item8094

The launch of a modal window from a previous one results in a loss of data on the previous one and therefore it is necessary to ensure that once a modal window has been launched, deactivate or make invisible the button or the icon which makes it possible to launch the one second since the first already launched. And in the task assigned to me, it is the help icon in the toolbar which contains a modal window once clicked. And I was asked to make the help icon invisible on the pages where the toolbar was called as a modal window so that no information could get lost.

As you can see in this image, once you click on the help icon, all the information already entered will be canceled because the help icon includes a modal window which will be launched on another modal window existing.

The solution I implemented is to hide the help icon as you can see in this image
