This application allows admin users to create programmed flash messages aimed towards one or multiple groups.

When a new flash message is created, it pops up on the screen for all the users from the selected groups, the first time they visit the wiki. After dismissing it, the message will be available below the page header.

The app can be accessed from the following two locations:

  • the Applications panel located on the left side of the page
  • the Other section from the global administration of the wiki




Flash messages index view in the app home


Flash messages index view from the Global Administration > Other > Flash Messages section



Create flash message

In order to create a new message, click Create button from the top of the page and the next step will display a list of available templates where you can find the one corresponding to flash messages.


Message structure

Each entry requires a start date from which the message will start being displayed, a list of groups to show it to and the actual message.
Optionally, you can provide an end date and set up the event as a recurring one.



In order to make an event recurrent, set the repeat property to "Yes".
After this step, a new settings layer will appear in order to configure the repeat period.
Choose your desired settings such as repeat interval, repeat frequency and the days of the week and you're set.
Be sure to keep an eye on the "Repeat summary" to have a human friendly overview of your settings.



Popup alert

The messages are displayed to a concerned user in form of a popup when the first page is loaded after the start time.


Header notification

After the user has viewed the message it is marked as seen and is only displayed in the top slider which contains the three most recent messages. Note that each message is shown for 10s after the slider goes to the next one.


Each of the three last messages is marked by a bullet in the right side of the flash bar located just under the header.
These bullets are used not only to display the position of the current message but to navigate through them as well.
