A Mendix widget that adds CSS classes determined by a microflow (or nanoflow) to elements determined by CSS selector.
It's useful in applications that need to determine styling based on arbitrary logic and change it dynamically in runtime:
- An example may be a multi-tenant app with different styling for different brands, depending on settings of the current user.
- Another use case would be to allow your users to choose between multiple theme or skins for your application, depending on their preferences.
- You can also improve accessibility by switching to styling with e.g. bigger fonts and cleaner layout with less distractions for users with visual or cognitive impairments.
Here you can find a simple yet beautiful sample app that switches its styling between light and dark depending on current user theme stored in Account entity.
(And here is the same app for Mendix 8.)
Place the widget inside your app and provide the following settings:
Microflow: A microflow that has no parameters and returns a string with CSS classes that should be added to target elements. Multiple classes can be seperated with a space.Nanoflow: Alternatively, you can use a nanoflow instead of microflow - as above.Target element selector: Optional CSS selector of target elements to add the classes to. If empty, the parent element of the widget will be used.CSS classes to remove: Optional CSS classes to be removed from the target elements. Multiple classes can be seperated with a space.
