VTEM Fancy Menu – one of the panels, which can be positioned left or right of the main screen of your page in the CMS Joomla. And to have only one of them, 2 at once will not work (why is this a question you need to ask the developers of this project).
VTEM Fancy Menu

In the settings there is a point, as the module is installed inside the panel. I persistently tried to introduce an external extension and insert it into the panel, but nothing happened, although I did everything as was written in the instructions for the component.
Otherwise, this extension helped me to establish a separate menu on your site – this can be the info panel, menu language switching and all that you need. But keep in mind that you must install the panel on the left or right of the screen, but about the panel at the top or bottom of why the developer didn’t think…
There are installation options of colors for background and links, and transition effects. In addition, you can set the size of the width, and the width of the paragraphs.
What can you summarize? In General a good solution if you require the panel to the side, but otherwise there are other modules that are more functional.
Installation of the side panel to the left or right of the screen.
Setting field width and transition effects.
Simple integration into the available settings and parameters.
