Hi Gonçalo,

You can encapsulate the container in an if widget.

Or in Extend Properties... Instead of 

If(IdentifierToInteger(GetUsers.List.Current.User.Attribute1) = 1,
"ShowContainer = True",
"ShowContainer = False")

put

If(IdentifierToInteger(GetUsers.List.Current.User.Attribute1) = 1,
"",
"display:none")

But CSS inline is not recommended... because

CSS and HTML should be kept separate. Inline styles are inefficient, harder to maintain, and make your HTML larger. 

I hope the above is useful to you!

Hello!

Additional to the answer already given:
Instead of creating a boolean that determines whether the container should be visible or not, you could write your logic directly into the "Visible" attribute of the container.
You can use the extended properties to define the style of a container based on a variable that you set somewhere else, e.g. in an action. But you can not change the value of a local variable in the extended properties.

Hi Gonçalo,

For the mentioned use-case the best implementation approach as per my understanding would be to conduct the server-side validation i.e. Server-side check, whether the logged-in user can access the menu option or not.

In order to implement the same (i.e. server-side check) then as mentioned by Mário, you will have to use the IF widget i.e. Wrap the Menu option within the IF widget with the valid condition. The IF widget (condition) is examined/executed/rendered in the server-side.

IF Widget Condition:

IdentifierToInteger(GetUsers.List.Current.User.Attribute1) = 1

For the mentioned use-case, defining the extended style property as well as defining the container widget's Display/Visible property is not that secure and is not considered as good practise. Let's say that the widget Display/Visible property is set to False value, in that case what happens under the hood is a inline-style i.e. style=" display: none;" is defined to the respective html element, which can be easily edited using the Browser inspect element feature. Hence, the restricted end-user can also access the menu option with a small tweak.

Hope this helps you!

Kind regards,
