Hi Ayman,
You can change the popup as well, there's a class in mendix for that,
you can use the developer window and get the class applied on the popul, and then override the whole
styling as per your requirement.
Hope it helps,
Let me know if you have any issues.
Hello Ayman,
You have the possibility instead of using this show message to show your own popup page, and in that page you can customize to whatever your needs are.
Hope it helps if you have any extra questions let me know.
The Show message popup cannot really be customized. Mendix uses the default Atlas UI modal for it and there are no options in the microflow to change its layout or styling.
If you want to change the look of the message the usual solution is to create your own popup page instead of using Show message. You can then open that page with Show page from the microflow.
On that popup page you can design everything yourself such as text layout icons colors buttons or spacing so you have full control over the UI. If you just need a slightly different design this approach is usually the easiest.
If this helps please mark the answer as accepted.
